Comparative Evaluation of Body Mass Index, Waist Circumference and Waist-To-Hip Ratio as Correlates of Glucose Intolerance among Rural Dwellers in Nigeria

This research investigates the comparative efficacy of Body Mass Index (BMI), Waist Circumference (WC), and Waist-to-Hip Ratio (WHR) as correlates of glucose intolerance among rural dwellers in Nigeria. Conducted as a descriptive cross-sectional study in Oyo State, Nigeria, the research involved adults aged 18 years and above. The study employed a multi-stage cluster sampling technique, selecting participants from rural communities. Exclusion criteria included pregnant women and those with known diabetes or medications affecting glucose metabolism. Anthro-pometric indices and blood glucose levels were determined using Hanson's weighing scale, a meter rule, and biochemical auto-analyzers. The BMI, WC, and WHR were utilized to assess obesity and abdominal adiposity. Blood glucose levels were measured for fasting and 2-hour post-prandial samples. Data analysis involved descriptive statistics and chi-square tests using SPSS version 26. Results from the study revealed demographic characteristics and medical history of participants. Findings indicated a significant association between anthropometric parameters and gender. Notably, WHR exhibited a strong correlation with glucose intolerance, emphasizing its potential as a predictor. The study also presented the correlation of BMI, WC, and WHR with blood glucose levels, categorizing participants into different risk groups based on these indices. This research contributes valuable insights into the effectiveness of BMI, WC, and WHR in predicting glucose intolerance among rural dwellers in Nigeria. The findings underscore the importance of tailored interventions for specific populations, considering regional variations in health determinants. Future research can build upon these results to develop targeted strategies for diabetes prevention and management in rural communities.本研究探讨了身体质量指数（Body Mass Index, BMI）、腰围（Waist Circumference, WC）及腰臀比（Waist-to-Hip Ratio, WHR）作为尼日利亚农村居民葡萄糖耐量异常相关指标的比较效能。本研究在尼日利亚奥约州开展描述性横断面研究，纳入18岁及以上成年人群作为研究对象。研究采用多阶段整群抽样技术，从当地农村社区招募参与者。排除标准涵盖孕妇、已确诊糖尿病患者以及服用影响糖代谢药物的人群。人体测量指标与血糖水平分别通过汉森（Hanson）体重秤、米尺及生化自动分析仪完成测定。本研究借助BMI、WC及WHR评估受试者的肥胖状态与腹部脂肪蓄积情况。血糖水平分别检测空腹样本与餐后2小时样本。数据分析采用SPSS 26.0版本进行描述性统计分析与卡方检验。研究结果呈现了参与者的人口统计学特征与病史信息。研究发现人体测量参数与性别存在显著关联。尤为值得关注的是，WHR与葡萄糖耐量异常呈现强相关性，凸显了其作为预测指标的潜在应用价值。本研究同时分析了BMI、WC及WHR与血糖水平的相关性，并依据上述三项指标将参与者划分为不同风险层级。本研究为评估BMI、WC及WHR在预测尼日利亚农村居民葡萄糖耐量异常方面的有效性提供了宝贵的学术见解。研究结果强调，需结合健康决定因素的区域异质性，为特定人群制定个性化健康干预措施。未来研究可基于本研究成果，针对农村社区开发糖尿病预防与管理的针对性策略。
