其他摘要：OBJECTIVE:To analyze if differences according to gender exists in theassociation between tooth loss and obesity among older adults.METHODS:We analyzed data on 1,704 older adults (60 years and over)from the baseline of a prospective cohort study conducted in Florianopolis,SC, Southern Brazil. Multivariable logistic regression models were used toassess the association between tooth loss and general and central obesity afteradjustment for confounders (age, gender, skin color, educational attainment,income, smoking, physical activity, use of dentures, hypertension, anddiabetes). Linear regressions were also assessed with body mass index andwaist circumference as continuous outcomes. Interaction between genderand tooth loss was further assessed.RESULTS:Overall mean body mass index was 28.0 kg/m². Mean waistcircumference was 96.8 cm for males and 92.6 cm for females. Increasingtooth loss was positively associated with increased body mass index andwaist circumference after adjustment for confounders. Edentates had 1.4(95%CI 1.1;1.9) times higher odds of being centrally obese than individualswith a higher number of teeth; however, the association lost significance afteradjustment for confounders. In comparison with edentate males, edentatefemales presented a twofold higher adjusted prevalence of general and centralobesity. In the joint effects model, edentate females had a 3.8 (95%CI 2.2;6.6)times higher odds to be centrally obese in comparison with males with morethan 10 teeth present in both the arches. Similarly, females with less than 10teeth in at least one arch had a 2.7 (95%CI 1.6;4.4) times higher odds ratioof having central obesity in comparison with males with more than 10 teethpresent in both the arches.CONCLUSIONS:Central obesity was more prevalent than general obesityamong the older adults. We did not observe any association between generalobesity and tooth loss. The association between central obesity and toothloss depends on gender – females with tooth loss had greater probability ofbeing obese.
