The historic and far reaching US supreme court decision supporting President Obama's health care reforms "largely unscathed" by the court decision is a significant victory for US public health professionals. There will be innumerable analyses of the decision, but a relatively concise and well written one is found in the Washington Post http://www.washingtonpost.com/politics/supreme-court-to-rule-thursday-on-health-care-law/2012/06/28/gJQAarRm8V_story.html .
Hidden in the final decision is that the 9 judges were split predominately on ideological lines, with four dissenting conservatives issuing a scathing minority report that questions numerous points of legality. Four liberal judges backing the formal court final decision. And a moderate single voice predominately leaning in favour of the decision. Such a fine line between passing and falling, based not so much on legalities but on ideology of the courts members.
And while a major political victory for Obama during an election year, the comment of his rival Romney was that the first thing he would do if elected would be to repel the reforms. The debate is not over, and may in essence come down to the single and solitary issue on which the November US election is run. Regrettably, the often dominate libertarian lifestyle may surpass the collective utilitarian good. Stay tuned.

Public Health in the News: People, Quebec Tobacco law suit, Gambling advertising, Cosmetic pesticides
Today is one of those
historic public health days. The US
Supreme Court will determine the constitutionality of providing health care to
all Americans. Put differently, it gets
to decide whether it is legal to let some 20% of our southern neighbours die
prematurely because of their personal financial barriers to health services, or
if there is anything to be said about the “We” in “We the people…. ”.
More on the decision in a future blog.
It was with concern
and dismay that the February stroke of Canada’s first and only Chief Public
Health Officer was announced several months after the event. Fortunately his quick mind, biting wit and perseverance
for Canada’s public health was not affected, the stroke limited to motor
functions in one of the lower limbs, or so the media reports say. May all of public Health wish David
Butler-Jones a full and fulfilling recovery.
For those following
the movement of key public health folks will note that Andrea Corriveau has
returned as the CMHO for the Northwest Territories after a three year stint in
a similar position in Alberta. James Talbot
has moved from deputy to CMHO for the province in a deserving career step that
has had its share of Albertan propensity to see public health folks move in and
out of favour.
Manitoba remains under
the leadership of Margaret Fast since the untimely departure of one of Canada’s
solid public health leaders in Joel Kettner.
No doubt there are other recent movements as well of lifelong public
health contributors to be celebrated.
Quebec has joined with
most of the other provinces in suing tobacco firms for unnecessary and
preventable health care costs associated with misrepresentation of the tobacco
product. In this case $60B. The story
in French at Lapresse
on Quebec tobacco law suit
Have you noticed the surge in advertising
related to gambling? No doubt one of
the next logical targets for public health advocates is to begin to constrain
this addiction, and government addiction to the revenue carried on the backs of
their citizens. The story from Ontario
about advertising that suggests that to get away from family you should go to
the casino hit a few raw nerves Forget
your family - The Star.
The Ontario College of Family Physicians
released an updated literature review on the impacts of pesticides in the
ongoing efforts to limit toxic effects OCFP and
pesticides. This group has been one
of the leading driver of pesticide reduction efforts in the country and clearly
has been effective in Ontario. There
efforts did not however sway the BC government committee that dismissed certain
scientists and used anecdotal evidence on the failure of weed management
strategies in a couple of situations as
sufficient rationale to recommend against a cosmetic pesticide regulation for
the province BC
cosmetic pesticide committee report.
The truth likely lies somewhere between this extreme positions. The Scandanavian “substitution” principle
adopted in Europe nicely handles the debate more than the much debated
“precautionary” principle. Substitution

Something to deaden the sweet tooth
A few years back we received a listing of the top 20
calorific drinks. A condensed version of
the list can be found at 20
most calorific drinks, the original supposedly in Men’s Health May
2010. Starbuck’s was rightly roasted
with 3 servings of their Vanilla Frappucinno (290 cal) , Peppermint While
Chocolate Mocha with whipped cream (660 calories) and White Hot Chocolate with
whipped cream (520 calories). A Dairy
Queen MooLattee coming in at 870 calories, Baskin and Robbins ice cream soda at
960 calories, McDonald’s triple thick chocolate shake at 1160 calories and the
cream of the crop was Cold Stone PB&C at an amazing 2010 calories.
This past week, a listing of ten top calorific deserts Top
10 desserts top
ten calorific deserts. Promoted by
the current North American bacon bit fad that has worked its way into a Burger
King sundae and tops the scales at a mere 510 calories per sundae. Dairy Queen blizzards (size not listed)
topping just over 1000 calories. Our
favourite for sharing amongst a whole table of friends is the Cheesecake
Factory Chocolate Tower Truffle Cake at 1679 calories, or about 40 calories a forkful by our calculations. Its the amazing Keg offering of a Carrot
Cake a la mode that tops in at 2344 calories to definitely take caution
of.
If your stomach is not already tumbling and heaving, how about taking a quick look just at volume and what has happened over the years in terms of normalizing soft drinks sizes. Megasizing soft drinks can be put in perspective by thinking 10-15 calories per 30 ml (ounce). so going from 200 ml - or about 75 calories, up to nearly a 4 litre cup (128 ounces) containing some 1500 calories - gives some sense of how marketing impacts individual choice.

There are very few naturally occurring drinks other than

to keep a bit thinner, cut the calories from what you drink, and steer clear of
the deserts.

Drowning in data – Making sense of health indicators.
Alice slipped down the rabbit hole and subsequently through
the looking glass into a world fantasized by a mathematician, filled with
symmetry and logic – and designed to please the literary masses. Her enduring stories have captured the
imagination of children and adults alike, and been the subject to innumerable
academic analyses. Her creator is the
envy of many scientists having mastered the ability to utilize storytelling to
convey logic and information. Although his
stories were predominately for entertainment, we are faced with similar
challenges in trying to convey stories told by reams of data that bombard the
wires.
This past week saw the start of the release of the most
recent round of the Canada Community Health Survey. Buried in the home site are links to
community or region specific information in addition to provincial data. CCHS 2011 release No doubt you as a reader can dig deep and
develop your own story about trying to access information. Humourously, Stats Can must have a bug in
their program for dating webpages, with posting years in the future being
commonplace. It is the sort of oversight
that undermines the importance of the data that was released.
There are some interesting stories to be told:
Good news
·
Tobacco use continues to trend downwards in both
genders and all age groups.
·
Physical activity continues to trend upwards in
most age-sex categories.
Not so good
news
·
Heavy alcohol consumption continues to trend
upwards in particular in middle aged persons.
·
Overweightness continues to trend upwards
although some suggestion that stabilizing and optimists might think there was some
reduction in the past couple of years.
·
The proportion of the population adhering to 5
fruits or vegetables daily is not trending in the right direction.

The case for, and the effectiveness of, action on determinants of health
Happy National Aboriginal Day - celebrate our heritage

monograph on cost of inaction While this is another descriptive study
looking at health inequalities, it attempts to put some monetary value to the cost

national level.
From the National Collaborating Centre on Determinants of Health

addressing determinants. Intersectoral
collaboration from NCCDH As has
become an increasing trend in systematic reviews, there is as much on why no
conclusions can be drawn because of poor methodology in most studies, as there
are gems to be found in the handful of studies that met the muster criteria for
inclusion.
Fear not, at least groups like Ontario Health Promotion have
issued an E-Bulletin on planning to action Ontario Health promotion e-bulletin which lays out a generic framework for action
on determinants without worrying too much on the lack of scientific foundation,
and encouraged collection of information on effectiveness as the process
proceeds.

Inequity - Communicating the message.
A piece from the Winnipeg Free Press is the latest item where
the media are supporting and driving the public health agenda of reducing
disparities. Winnipeg
Free Press June 18, 2012 Masters of
storytelling, such heartfelt pleas echo the public displays of discontent in
the Montreal student strike, the Occupy movement and even the efforts of
doctors for fair taxation Equity
and taxation – the status quo is being whittled away.
Yet, despite the crashing Greek economy with unemployment
approaching 25%, the conservative leaning incumbents were returned with the
plurality and asked to form a coalition government. This contrasts with the
election of the left leaning French Socialist party presidential candidate.
As powerful as the media can be in expressing the message –
it is further enlightening to read the personal reactions to the Winnipeg piece. No wonder there is such resistance to
addressing the increasing disparity in the country. Clashing values of personal happiness against
societal altruism are played out in the words of individuals responding to the
article.
Just as the G20 countries prepare to meet in Mexico to
further discuss the current global financial crisis that has banks and
businesses suffering such that public tax dollars are being poured by the
billions in corporate welfare while personal welfare programs are cut to
balance budgets. Buried deep in the throes
of the bureaucracy is this December 2011 OECD report Divided we fall: an overview of growing income inequalities an economic analysis of inequality
globally. A Canada specific summary is
available at Canada
report, US at US
report
Note Figures 9 and 11 – which display Canada’s inequality in
respect to other developed countries.
Figure 11 (pasted below) adjusts for the impact of universal health care and makes Canada look as good as any of measures. Using any
of the three Gini coefficient measures in the document, Canada remains higher
than the OECD mean – and higher means more inequality. (for more on Gini
coefficient Gini
coefficient September 14, 2011 ). Figure 12 also below, is most disconcerting for North
Americans as it shows the increasing proportion of wealth held by the top 1% of
income earners, with the US in the not so enviable position of number 1 and
Canada number 3.
Why, in the midst of such forces as left wing leaning social
and health professionals and right wing leaning economists – both of whom have
been signalling warning signs of the dangers of propagating the long term trend
of increasing disparity, do we continue to have political decisions which fly
in the face of facts? Truthfully, the OECD
report is dry, unexciting, lacks story and personification – reminiscent of
many public health reports. While the
number crunchers may get thrills from reading the report, it likely had little
impact on policy decisions in any OECD country.
Good governance is the ability to provide leadership amidst
conflicting value structures with an aim for the greatest benefit. While the media may be the new modality messaging
inequality, the media have also been the drivers of populism as the goal of governance
rather than leadership. There was a
notable subpiece to the Montreal student demonstrations on the success of the
new generation to win the use of new communications media http://www.ctv.ca/CTVNews/Canada/20120618/social-media-quebec-student-protests-120618/
. The press have long influenced public
opinion and have been the puppeteers of political winners and downfall of
political losers. We in public health
have a lot to learn about moving from number crunching to pulling at heart
strings.

Father's (and Mother's) Day celebrations - Demographic changes as presented by Dr. Hans Rosling
June 17th is Father’s Day, and the second of the
parental celebrations.
Please take this as a chance to celebrate both Mother and Father's Days and to
discuss the changing dynamics of family structure in Canada and globally. Statistics Canada has special releases on
the changing role of mothers Stats Can
and Mother's Day and fathers Stats
Can and Father's Day. Note the very
significant increases in dual income families and single income families led by
mothers over time.
For those that have followed the great discussions over the
decades on family planning and control of global population growth along with
the Malthusian predictions of overpopulation and nonsustainability will welcome
recent demographic information. Considerable progress has been made in many
countries, with the global fertility rate now resting close to global replacement
levels.

Good news and bad news on what youth are smoking and drinking
Our friends to the south are very more diligent in collecting
information on the health and wellbeing of their population. Canada has much to learn and emulate. A report released last week is based on an ongoing
youth risk behaviour surveillance study.
The study comprises work from the national surveillance program, 43
state surveys and 21 large urban school area surveys US behaviour youth survey. Are you envious yet? The down side, is the report rarely puts data
into a temporal context. Just like with
patients, it is measuring changes that are critical to management of the
population’s health.
The study and the Canadian comparators are rich information
and worth using as a benchmark for surveys in provinces and regions.
Work in both countries confirms something most would have suspected. Regular tobacco use behaviour in US youth has
reached a relative low at 10.2% daily use in the last 30 days with any tobacco smoking
use at 18.1%. This is good news. On the other hand, marijuana use in the last
30 days was at 23.1%. Officially,
marijuana use has become more prevalent than tobacco.
Lest we forget the third of the major psychoactive substances,
alcohol. Consumption being illegal for youth
under 21 in the US with provinces at either 18 or 19 years of age. US youth use
of alcohol in the previous 30 days was the highest of the three substances at
38.7%. Alcohol consumption by youth seems to be decreasing amongst this US
population .
Within Canada we have the Youth smoking survey 2010-2011 Youth
smoking survey 2010-2011 which shows tobacco use at 10% use in past 30. This survey also asks about alcohol and drug
use with rates reported at 45% use of alcohol in the last year, and this is also
appears to be decreasing. Past year
cannabis use reported at 21% and also supposedly decreasing. Note
that question format and time frames make comparison to the US survey difficult
but suggestive that youth in both countries have similar risk profiles.
The Canadian drug and Alcohol Use Monitoring Survey provides
some information on youth (ages 15-24) CDAUMS but does not provide directly comparable
statistics to the US youth behavioural survey . Cannabis consumption in the past year – 25.1%. Alcohol
consumption in past 30 days – 52.3%. Noting
that these numbers would at least appear consistent with the youth survey data
given a slightly different age group.
Here rests the public health dilemma. We have different approaches to efforts to
control and regulate tobacco, alcohol and marijuana, the former being legal,
the later still considered a criminal offense to have possession of. Alcohol supposed
not legal for consumption for youth.
Relative success has occurring through concerted efforts to reduce
tobacco and alcohol, yet efforts to control marijuana use are limited by lack
of information, lack of legitimacy and significant illicit profit compared to
regulated substances like tobacco and alcohol.
While marijuana may not have the same health risks associated with
its use, it is not something to be promoted or encouraged – but controlled.

Dietary modification to improve the public's health. New news to chew on.
Mayor Bloomberg’s pronouncement that he hopes to ban large
sized soft drinks has caused a flurry of diet related activity. No reference
here to the mayor’s comments as the blogosphere is filled with opinions on the
relative value, morals and expected impacts of such a ban. Our only comment is it was NYC’s 2006 ban on unsaturated
fats that led the wave across the country and resulted in considerable benefit
in reduced unhealthy fat consumption.
Let us begin by reiterating that there is no clearly
demonstrated effective long term cure for overweight and obesity. The consistently most effective intervention
is bariatric surgical intervention which is unlikely to be widely endorsed for
other than the morbidly obese.
So the issue of obesity gives great fodder to fill lay
magazines, morning talk shows and fuel for weight loss schemes – all of which
are thriving. This blog is no less
guilty than others of trying to weigh into the fray. healthy
environments and obesity, losing
weight low
sodium diets, Motivational
interviewing for obesity, obesity
and political ramifications .
Three more items to expand the discussion. To reinforce what we all know is a study
demonstrating that Americans know it as well.
Losing weight is tough, and tougher than completing their taxes. The original article at Science
daily on losing weight. The executive
original work can be found at food
information council survey and with the encouragement that primary review
of such reports is good practice. Lost
in the press release headlines about how difficult it is to lose weight, are
some good tidbits of information on the current state of American health on
food intake, obesity and physical activity. It is challenging on the site to
actually determine the methodology other than an on-line survey which may
contribute to certain biases.
A review that confirms that there is up to a 14% benefit in
cardiovascular events in men only in modifying dietary fat that resulted in
lower triglycerides and LDL. There was
no benefit noted in all cause or cardiovascular mortality. The full review (a 2011 update of the 2001
review) is available within the Cochrane database – the abstract at Dietary modification for
cardiovascular events.
Lastly is a piece on the reduced risk of childhood obesity
amongst infants born vaginally compared to Caesarean section.
Biologically this is being promoted by changes in GI tract flora. An interesting avenue for additional
research. Is anyone aware of a good
retrospective study looking at adult weights at birth type? C-section
and childhood obesity.
Diabetes and endocrine disorders continue to be some of the
few causes of death and disability that are increasing, and obesity is a
significant risk factor to the development of these conditions. The solution is prevention, but in working
towards prevention, we need also grapple with early intervention and in
intervention when manifest problems are developing.

Harm Reduction and the politics of language.
Anyone who interfaces with the federal government will have noted its pathological phobia with the term “harm reduction”. That generic set of two words that inferences that as humans we sometimes chose to engage in activities that have a higher risk for hurting or potentially even killing ourselves, and that we can reduce the likelihood of harm by invoking any variety of activities. Helmets for cyclists and boarders, barrier and contraceptive protection for sexual intimacy, seat belts in cars, wearing sunscreen, donning a parka during the winter – the list can go on and something each of us engages in constantly in our lives without a second thought.
The more specific definition that has caused angst suggests harm reduction is an activity limited to persons who suffer from addictions, often but not exclusively associated with illicit drugs. This blog has spoken to many types such as supervised injection sites, cannabis decriminalization, needle exchange/distribution, methadone distribution programs, safer alcohol consumption guidelines, alcohol distribution in some homeless housing initiatives. Some of these you may be comfortable with, others might cause some to raise their shackles as a stretch of their moral frameworks.
Health is a science and should be driven by evidence. From a health perspective, many of the listed harm reduction for addictions result in a demonstrable benefit for individual and societal health. Most have a net cost reduction to the taxpayer through deferred health and social services. So they should be an easy sell. Differing perceptions of morality, religion and politics are often barriers to doing the right thing. So how has the current government influenced the discussion on harm reduction.
So lets do an experiment and obtain some evidence. Go to a government home page – we tried Health Canada and PHAC. Take a search on the term “harm reduction. Respectively the searchers returned 668 and 340 document references. Now try to learn about where public government documents reference harm reduction. Most of the material is related to pesticide and product regulation so finding relevant materials is not as straightforward. If you expand the search by collection on the right hand menu and pick “health concerns”, most of the addictions materials are listed, some 177 documents. The PHAC site is more generic and most of the material returned is related to addiction concerns. Presented as a linear time trend as below:
As a reminder, Harper was elected in 2006, reelected in 2008 and obtained a majority government in 2011. Minister Aglukkaq was first elected in 2008 and immediately began her long standing term as Minister of Health. PHAC supposedly operates at arms length from the government, but is somewhat handcuffed by federal political structures.
So, in a world where governments have long used manipulation of language and words to meet their own purposes – here is clear evidence of political ideology affecting the science of health and the operations of Health Canada. And clear evidence of the social impact that governments can have by imposing views and curtailing dialogue – reminiscent of dictatorial regimes.

Coffee, Tea or ??
Products that are widely consumed are excellent targets for
health claims, but the very nature of consumption patterns make epidemiological
investigation challenging, and if absolute associations are weak, then
identification of potential benefit or risks can be a lifelong career. The identification of the health effects of tea
and coffee are prime examples.
Since the mid-1970’s numerous publications have sought the
definitive relationship, and many of these studies were published in no less an
esteemed journal as the New England
Journal of Medicine. The wonderful
series of publications makes an excellent course in critical appraisal of health
publications as conflicting results appear to arise from similarly executed investigations.
The major challenge being the association between stimulate consumption and
certain other behaviours such as smoking, caloric intake, alcohol consumption
and socioeconomic status.
The latest in the series of hundreds of North American and European
coffee studies is also published in this esteemed journal and looks at some 5
million person-years of follow-up and death events in 33,000 men and 19,000
women. NEJM study
on coffee and mortality
Tea drinkers fear not, the literature is just as rife with
more interest from predominately tea drinking countries. The subject received a rigorous review that
explored some 40 studies also covering a few million person-years of exposure and
a variety of epidemiological study methods.
The analysis was more specifically focused on cardiovascular disease and
diabetes outcomes tea
and health outcomes review article.
So the results, or at least what is available and comparable.

Perhaps even more reflective of the great debate globally,
no study mentions adjusting for consumption the other common beverage. The assumption that both coffee and tea drinkers
are exclusive in their habits is reflective of the biases within the literature. Also notable is the extensive discussion of
what constituents of tea are perceived as beneficial, with the absence of such
debate in the coffee literature.
Such investigations will continue to populate the medical
literature for decades to come until someone convinces a naive group of youth to
be randomly allocated to cohorts of coffee, tea or neither and subject them to
decades without allowing for their choice of stimulant. Stated otherwise, the question and the
subject will continue to percolate and simmer.

DrPHealth was one of numerous commenters
on the risks of overscreening
DrPHealth May 14 in relation to the release of prostate cancer screening
recommendations that clearly identified unintended risks as a point of
concern. BMJ continued the barrage and expanded the conversation to the
whole issue of overdiagnosis. The well
written commentary clearly puts the risks of the health care system as a
significant cause of avoidable mortality and morbidity. BMJ

estimated overdiagnosis rates noted in Table 1.
Follow this debate over the next few years. Those who work in the system are likely very
familiar with both the problem, and the avoidance behaviour demonstrated by
professionals who see errors of omission as more problematic than errors of the
system. “Better to have tried and failed than to not have tried at all” (often paraphrased from Tennyson)
Poverty report
card From Ontario is a report
card on progress towards implementing the provincial poverty reduction action
plan. Long on baseline data and short on
evidence of progress – the report card at least is an attempt to keep the
issues alive and on the public agenda.
Timing is everything as the baseline data are prerecession, and the
evidence shows as much the impact of the recession as efforts to ameliorate
poverty. Keep it up. Ontario

a regional bias, hidden in the report card are some great provincial comparisons. Jump to the appendices and see how provinces

detracts from the value of the report card as the gradings are based on rank
ordering rather than progress towards the best practices. Tobacco

Health Index and the Ultraviolet Index.
A substantive question is on the relative benefit of such tools which are
the mainstay of weather forecasters and TV weatherpeople. The entry is a review out of Germany of the
known effectiveness of the UV index and suggesting relatively low awareness and
behaviour change impact. Not surprising
as what other indices show is that they don’t seem to affect decisions today,
but the cumulative messaging can result in substantive behaviour changes and
long term risk reduction – clearly an area for lots of study. Review of UV Index
Prevention of perinatal
Hepatitis B transmission: Just
to slip in something is a potential practice change. The traditional approach to babies born to
mothers known to be Hepatitis B antigen positive has been the provision of
Hepatitis B Immunoglobulin. A proposed
alternative approach is the provision of lamuvidine (antiviral) during late
pregnancy and showing good results, comparable or better than HBIG provision. Warning
the review article is not the easiest to read
Lamuvidine
vs HBIG for perinatal Hep B transmission .

CPHA – Time to support our organization.
With the CPHA meeting just a week away, a reminder to all
Canadian public health workers of the need to support the organization. At a 102 years of age, its longevity exceeds
most of the other health organizations in the country. CPHA is feeling the pressure of both federal
cuts and a long standing dependency on coordination of international projects
which began to be eroded over a decade ago, and as with many organizations was
slow to respond to the impending fiscal reality. It is however still the preeminent public
health organization in the country and all public health workers should
consider actively being involved. To
this should be added the benefits to align the professional specific
organizations under the umbrella – the Public Health Physicians of Canada have
attempted to do this for the past 4-5 years with some success, it is time for
groups like CIPHI (Public health inspectors) and CHNAC (public health nurses)
to lay down professional jealousies and come together in defence of the organization
from which they were originally conceived.
For our international colleagues, while this post relates to a short term domestic issue,
CPHA has been a major driver behind the World Federation of Public Health Associations
whose current president Jim Chauvin is a long standing director of policy with the CPHA
head office. He is not the first Canadian to chair this relatively young group either. WFPHA home page
Some of the great work that Canadian public health workers
depend upon that requires our support, more of which can be found just by
suffering the CPHA website at CPHA
home page
Canadian Coalition for Public Health in the 21st
Century – a network of 35 health organizations that stand together in
advocating for health in Canada. The
organization has been in place for 9 years
Canadian Coalition for Immunization Awareness and Promotion
– headed from the CPHA offices, this is the group that keeps promoting
immunization awareness and providing the great resources that most public
health workers depend on daily.
CPHA used to house the Canadian Aids/HIV clearinghouse until
funding was eliminated a couple of years back – it still maintains a portal to
many on-line resources.
Canadian Journal of Public Health – a foundational document
that remains one of the few resources for public health professionals focused
predominately on Canadian public health practice.
Annual conference – an enjoyable location where academics,
policy makers, senior officials, front line staff can come together as equals
and discuss the issues of public health in Canada.
And many more, including numerous portals, services, sales
and advocacy activities.
CEO Deb Lynkowski has done a marvellous job over the past
few years in opening transparency of the organization and attempting to bring
an approach to fiscal sustainability in a resource compromised
environment. The retirement of assistant
CEO Janet McLaren who quietly in the background made things happen within the
organization was a significant loss but with well wishes for her
retirement. Other key office staff who
have weathered the years and remain dedicated to the mission of CPHA include
the directors Greg Penny (knowledge), Ian Culbert (communications) and Karen
Craven (CJPH assistant editor). These are the unsung heroes of the Canadian
public health system.
If you are a member – thank you. If not, it is not a huge financial commitment
but one that reaps benefits for all Canadian public health workers and through
them, to all Canadians. Not in Canada –
support your national public health association, it is the backbone for public health
work globally.

What conclusions can you draw? Here are ours:
Canadian readership has either
dropped or moved to direct email for which no tracking is available
Issues of social justice seem to have
the greatest popularity
Niche topics can be either very
successful (Telehealth and healthy built environment), or very disappointing
(weather and health series). (Posting specific information is available
for total views)
Canadian specific content which is
the focus of the blog is not attracting the attention that was the messaging
intent
Twitter and Link-in posting are not
nearly as effective as they were
