The present study was aimed at analyzing the association between elderly women's perception of their nutritional status (overweight and obesity) regarding their overall health in low-income neighborhoods in Curitiba, Brazil.
The sample consisted of 449 elderly women participating in the Idoso em Movimento program in low-income neighborhoods in Curitiba. Body weight and height were measured to calculate their Body Mass Index (BMI); 25 kg/m(2) and 30 kg/m(2) cut-off points were considered for determining weight status regarding being overweight and obese, respectively. A specific question concerning elderly health perception was used for classifying them into negative or positive health perception categories. Kruskal-Wallis and Chi-square tests were used for data analysis in terms of descriptive statistics. Binary logistic regression was used for analyzing the association between weight status and health perception, controlling for age, economic status, marital status, years spent in formal education, occupational status and time spent on physical activity per week. A 5 % significance level was used.
Obesity was significantly associated with a perception of suffering negative health (p<0.05). Obese elderly women were twice as likely to have a negative perception of their health. Being overweight was not associated with a negative perception of health.
Decreasing obesity in obese low-income elderly is paramount for promoting better health perception in this risk group.
本研究旨在分析巴西库里蒂巴低收入社区老年女性对自身营养状况（超重和肥胖）与整体健康之间关联的认知。
样本包括449名参与库里蒂巴低收入社区“老年运动”项目的老年女性。测量体重和身高以计算她们的体重指数（BMI）；分别采用25千克/平方米和30千克/平方米的切点来确定超重和肥胖的体重状况。使用一个关于老年健康认知的特定问题将她们分为负面或正面健康认知类别。在描述性统计方面，采用Kruskal-Wallis检验和卡方检验进行数据分析。二元逻辑回归用于分析体重状况与健康认知之间的关联，同时控制年龄、经济状况、婚姻状况、正规教育年限、职业状况和每周体育活动时间。使用5%的显著性水平。
肥胖与负面健康认知显著相关（p<0.05）。肥胖老年女性对自身健康有负面认知的可能性是其他人的两倍。超重与负面健康认知无关。
降低肥胖低收入老年女性的肥胖率对于改善这一风险群体的健康认知至关重要。
