Temporal trends in cardiovascular disease risk factors among white, South Asian, Chinese and black groups in Ontario, Canada, 2001 to 2012: a population-based study.

Chiu M, Maclagan LC, Tu JV, Shah BR - BMJ Open (2015)

Bottom Line: The prevalence of hypertension increased the most among black females.Smoking prevalence decreased by more than 20% among South Asian, Chinese and white females.Awareness of the direction and magnitude of these risk factor trends may be useful in informing targeted strategies for preventing cardiovascular diseases in multiethnic populations.

Temporal trends in age- and sex-standardised prevalence of overweight/obesity, by ethnicity and sex. Data were derived from the Ontario components of Statistics Canada's Canadian Community Health Surveys. Estimates were age- and sex-standardised to the 2001 Ontario Census population using 5-year age categories, and weighted by the survey sample weight. Definitions: Overweight/obesity, body-mass index ≥25 kg/m2; Obesity, body-mass index ≥30kg/m2.

BMJOPEN2014007232F2: Temporal trends in age- and sex-standardised prevalence of overweight/obesity, by ethnicity and sex. Data were derived from the Ontario components of Statistics Canada's Canadian Community Health Surveys. Estimates were age- and sex-standardised to the 2001 Ontario Census population using 5-year age categories, and weighted by the survey sample weight. Definitions: Overweight/obesity, body-mass index ≥25 kg/m2; Obesity, body-mass index ≥30kg/m2.

Mentions: Figure 1 displays the temporal trends in the prevalence of major cardiovascular risk factors by ethnicity. Between the periods of 2001–2004 and 2009–2012, the prevalence of diabetes increased from 6.7% (95% CI 4.4 to 9.2) to 15.2% (95% CI 11.7 to 18.0) among South Asian males and from 6.3% (95% CI 3.8 to 9.5) to 12.2% (95% CI 8.0 to 15.8) among black females—representing 2.3-fold (p=0.0001) and 1.9-fold (p=0.02) increases, respectively (see online supplementary table S1). The prevalence of obesity increased in all ethnic and sex groups during the study period; with the largest relative increases observed among males of Chinese (2.1-fold increase, p=0.04) and black (1.7-fold, p=0.06) descent. By the end of the study period, the prevalence of overweight/obesity exceeded 50% for white and black males, and was 46% for South Asian males (figure 2). Smoking prevalence declined by more than 20% among South Asian, Chinese and white females. Among white males and females, the prevalence of diabetes, hypertension, overweight/obesity increased, while smoking prevalence improved (see online supplementary tables 1 and 2).
