摘要
背景:儿童营养不良,包括营养不足和营养过剩,在包括南非在内的许多低收入和中等收入国家仍然是一个重大的公共卫生问题。了解南非农村青少年的人体测量特征和肥胖预测因素对于告知有针对性的公共卫生干预措施至关重要。目的:本研究旨在评估南非埃利斯拉斯农村11-17岁儿童的营养状况,并确定肥胖的预测因素。环境:该研究于2021年1月至2021年12月在南非农村地区Ellisras进行。方法:共1217名青少年(男生612名,女生605名)参与研究。收集人体测量数据,包括身高、体重和身体质量指数(BMI)。采用多变量回归分析确定与肥胖相关的因素。结果:43.10%的儿童体重过轻,其中男孩(64.57%)高于女孩(35.43%)。超重和肥胖的总体患病率较低(0.41%),女孩(80%)比男孩(20%)受影响更大。男孩的平均身高(154.79 cm)略高于女孩(154.60 cm),而女孩的平均BMI (16.41 kg/m2)高于男孩(15.81 kg/m2)。多因素回归分析显示,15-16岁青少年的肥胖几率显著高于11-12岁青少年(校正优势比[AOR] = 2.10, p < 0.001)。此外,女孩的肥胖几率明显高于男孩(AOR = 2.80, p < 0.001)。结论:该研究突出了南非农村青少年中营养不良的双重负担,体重不足和新出现的肥胖非常普遍,特别是在女孩中。贡献:这些发现强调了有针对性的营养干预的必要性,特别关注15-16岁的青少年和女孩,她们肥胖的风险更高。
BMI-based nutritional assessment of children aged 11-17 years in rural Ellisras, Limpopo province.
Background: Childhood malnutrition, including both undernutrition and overnutrition, remains a significant public health concern in many low- and middle-income countries, including South Africa. Understanding the anthropometric characteristics and obesity predictors among rural South African adolescents is crucial for informing targeted public health interventions.
Aim: This study aimed to assess the nutritional status of children in rural Ellisras, South Africa, aged 11-17 years, and to identify predictors of obesity.
Setting: The study was conducted in Ellisras, a rural area in South Africa, between January 2021 and December 2021.
Methods: A total of 1217 adolescents (612 boys, 605 girls) participated in the study. Anthropometric measurements, including height, weight and body mass index (BMI), were collected. Multivariate regression analysis was used to identify factors associated with obesity.
Results: The findings indicated that 43.10% of children were classified as underweight, with a higher prevalence among boys (64.57%) than girls (35.43%). The overall prevalence of overweight and obesity was low (0.41%), with girls (80%) being more affected than boys (20%). Boys had a slightly higher average height (154.79 cm) than girls (154.60 cm), while girls had a higher average BMI (16.41 kg/m2) compared to boys (15.81 kg/m2). Multivariate regression analysis revealed that adolescents aged 15-16 years had significantly higher odds of obesity (adjusted odds ratio [AOR] = 2.10, p < 0.001) compared to 11-12-year-olds. Additionally, girls had significantly higher odds of obesity than boys (AOR = 2.80, p < 0.001).
Conclusion: The study highlights the dual burden of malnutrition among rural South African adolescents, with a high prevalence of underweight and emerging obesity, particularly among girls.
Contribution: These findings emphasise the need for targeted nutritional interventions, with special attention to adolescents aged 15-16 years and girls, who are at a higher risk of obesity.
期刊介绍:
The Journal of Public Health in Africa (JPHiA) is a peer-reviewed, academic journal that focuses on health issues in the African continent.
