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.
