Angst ridden 30-something Bridget Jones starts each day on the scale, obsessively tracking her weight against social expectations. She vows to become svelte, only to confide her personal dieting failures to her diary the next morning.

Author Helen Fielding鈥檚 Bridget Jones鈥� Diary resonated with women near and far, even catapulting her London-based heroine onto the cinematic screen.

Like Bridget, Sara Kirk hails from the United Kingdom and could be described as being fascinated with weight management. If they ever had the chance to meet over coffee (or given Bridget鈥檚 lifestyle, a martini) Sara would have some comforting advice: 鈥淚t鈥檚 not all your fault, Bridget.鈥�

If Bridget is taken aback at the suggestion, she wouldn鈥檛 be alone 鈥� it runs contrary to conventional wisdom.

鈥淔or many years, we鈥檝e looked at weight as an individual problem. It鈥檚 a personal responsibility 鈥� willpower, call it what you will. The general consensus still is that it is an individual problem, one that should not be medicalized,鈥� says Dr. Kirk. 鈥淎ctually, there鈥檚 a huge body of literature that鈥檚 coming out now that says we need to look at the culture and the environment.鈥�

Dr. Kirk is a former registered dietician and an expert on the management and prevention of obesity. The new Canada Research Chair in Health Services Research is with 国民彩票鈥檚 School of Health Services Administration and is cross-appointed with the IWK Health Centre.

The general consensus still is that it is an individual problem, one that should not be medicalized,鈥� says Sara听Kirk. 鈥淎ctually, there鈥檚 a huge body of literature that鈥檚 coming out now that says we need to look at the culture and the environment.鈥�

鈥淚n my research I鈥檓 trying to understand what it鈥檚 like for the person who has a problem to go to a doctor and then be told it鈥檚 your own fault 鈥� just eat less and do more activity 鈥� because that鈥檚 how we treat obesity. But we must also recognize that there are other things at the core, our policies need to change,鈥� she says.

Daily life has changed so dramatically in the past 50 years that most people have little opportunity for built in activity. The western 鈥榙riving and convenience culture鈥� is seductive. 鈥淎s humans, we want to take the easy way and it鈥檚 very hard to go against that,鈥� she says.

Even the pace of change offers cause for concern. In the past 15 years, the number of people who are overweight or obese in Atlantic Canada has doubled 鈥� and Nova Scotia now has one of the highest rates of obesity in Canada. 鈥淚f I look at Nova Scotia, slightly over 60 per cent of adults, and one in three children, are overweight or obese 鈥� and it takes about a thousand lives a year,鈥� she says. 鈥淐ertainly, with people developing a weight problem, it鈥檚 so easy to do now that it鈥檚 almost becoming normal.鈥�

Her first Halifax-based study, funded through the IWK Health Centre, and focusing on the 鈥榦besiogenic environment鈥� in childhood, is up and running. The study is looking at the factors in the environment 鈥� access to green spaces, access to food 鈥� that may contribute to obesity in children in Nova Scotia. The next step is to measure the body mass index (BMI) of children and map this according to the characteristics of the environment. 鈥淲e鈥檙e going to identify factors in the environment that actually contribute to childhood obesity, and then ask 鈥榗an we do something to change the way that people respond to the environment?鈥欌��

She is also co-applicant (along with Renee Lyons, Atlantic Health Promotion Research Centre and Jill Grant, of Architecture and Planning) on another study, funded by the Heart and Stroke Foundation of Canada and CIHR. This research will use cutting-edge technology, including global positioning systems (GPS) to understand how children interact with their environments and exploring the intersection of community planning, physical activity and body weight. Studying the interaction of behaviour and the environment will help prevent obesity.
