OBJECTIVETest the hypothesis that diabetes and related risk factors are more common among female than male Zuni Indians.
RESEARCH DESIGN AND METHODSWe conducted a population-based, cross-sectional survey of the Zuni Indians aged 5 years. We used households within neighborhood clusters as the sampling frame. We administered a questionnaire, collected blood and urine, and measured height and weight. Self-reported diabetes was used to assess previously diagnosed diabetes. Participants without a prior history of diabetes were classified as having newly diagnosed diabetes if they had HbA1c >7.0% or random glucose 11.1 mmol/l during the survey.
RESULTSThe prevalence of previously diagnosed diabetes among Zuni Indians aged 5 years (n = 1,503) was higher among female Zuni Indians (16.7% [95% CI 14.119.3]) than male Zuni Indians (9.7% [7.412.1]) (P < 0.001). The prevalence of newly diagnosed diabetes was similar among female Zuni Indians (2.4% [1.43.4]) and male Zuni Indians (2.4% [1.23.6]). The prevalence of previously and newly diagnosed diabetes was higher among female Zuni Indians (19.1% [16.421.9]) than male Zuni Indians (12.2% [9.514.8]) (P < 0.001). The prevalence of obesity was higher among female Zuni Indians (34.3% [30.937.7]) than male Zuni Indians (21.5% [18.424.7]) (P < 0.001). Obesity was associated with diabetes among female and male Zuni Indians. Physical inactivity was more common among female Zuni Indians (44.2% [40.747.8]) than male Zuni Indians (35.1% [31.538.7]) (P < 0.001). However, physical inactivity was not associated with diabetes among either female or male Zuni Indians. Gestational diabetes was a risk factor among female Zuni Indians.
CONCLUSIONSAmong the Zuni Indians, the prevalence of diabetes was 57% higher among female than male members of the population. Culture, tradition, and lifestyle differences may contribute to the higher prevalence of diabetes and obesity among female Zuni Indians.
