Prevalence of Overweight and Obesity in a Woodland Cree Community: 14 Year Trends

      ABSTRACT

      OBJECTIVE

      To estimate the current prevalence of overweight/obesity in a Woodland Cree First Nations community and examine trends over time.

      METHODS

      Anthropometric measures (waist circumference [WC], height and weight) were used to determine the prevalence of overweight/obesity. Results were compared to those obtained in 1991.

      RESULTS

      Data from 289 males and females aged 7 to 82 years (mean 31.0±16.5 years) were compared to 316 participants aged 7 to 78 years (mean 24.6±15.6 years) from 1991. In 1991, 24% of youth were overweight/obese, compared to 26% in 2005. Among adults, 74% were overweight/obese in 1991, compared to 68% in 2005. Differences were not significant for youth or adults. WC increased with age in males and females. Mean WC for all female age groups exceeded the Canadian guidelines cutoff; WC for all male age groups was below the guidelines cutoff, with the exception of those aged over 65.

      CONCLUSIONS

      High prevalence rates of overweight/ obesity among adults remained over time, particularly among females. The concern for unhealthy body weights among females suggests intervention programs targeting women are needed. Future research exploring community-specific causes of overweight/obesity to identify local belief systems and lifestyle practices is required.

      RÉSUMÉ

      OBJECTIF

      Estimer la prévalence actuelle de l'embonpoint/ obésité dans une communauté de la Première nation crie de Woodland et examiner son évolution dans le temps.

      MÉTHODES

      Des mesures anthropométriques (tour de taille [TT], taille et poids) ont servi à déterminer la préva-lence de l'embonpoint/obésité. Les résultats ont été com-parés à ceux obtenus en 1991.

      RÉSULTATS

      Les données obtenues auprès de 289 per-sonnes des deux sexes de 7 à 82 ans (âge moyen de 31,0±16,5 ans) ont été comparées à celles obtenues en 1991 auprès de 316 participants de 7 à 78 ans (âge moyen de 24,6±15,6 ans). En 1991, 24 % des jeunes avaient de l'embonpoint ou étaient obèses, par rapport à 26 % en 2005. Chez les adultes, la prévalence de l'embonpoint/ obésité était de 74 % en 1991, par rapport à 68 % en 2005. Les différences n'étaient significatives ni chez les jeunes ni chez les adultes. Le TT augmentait avec l'âge dans les deux sexes. Chez les femmes, le TT moyen dans tous les groupes d'âge était supérieur au seuil recommandé dans les lignes directrices canadiennes; chez les hommes, le TT était inférieur au seuil recommandé dans tous les groupes d'âge, sauf chez les hommes de 65 ans et plus.

      CONCLUSIONS

      La prévalence de l'embonpoint/obésité est demeurée élevée au fil des ans, surtout chez les femmes. Les inquiétudes liées à la prévalence de l'embonpoint/ obésité chez les femmes font ressortir la nécessité de programmes d'intervention s'adressant aux femmes. Des recherches devront être menées pour déterminer les causes de l'embonpoint/obésité à l'échelle communautaire, soit les croyances et les habitudes de vie qui y contribuent.
