BACKGROUND/OBJECTIVES: Brazil and Mozambique face similar socioeconomic challenges, including common indicators of undernutrition and overnutrition among children. This study evaluated the similarity degree of the anthropometric and body composition variables of Brazilian and Mozambican children by using the Jaccard index.
METHODS
A total of 1831 children of both genders aged 7-10 years from three Brazilian cities (Recife, Vitoria de Santo Antao, and Lagoa do Carro) and three Mozambican cities (Maputo, Boane, and Inhambane) participated in this study. Anthropometric (height, body mass, and waist circumference) and body composition (body fat percentage [%BF], lean mass, and fat mass) variables were measured and the Smoothed Jaccard Index Surface (SJIS) was used to evaluate the similarity degree.
RESULTS
Brazilian children were taller and heavier and had a higher %BF and fat mass than Mozambican children. Children living in urban areas were taller than those living in rural zones in both countries. Brazilian and Mozambican children showed high similarity only between %BF and lean mass. Children from Recife and Maputo had high similarities among waist circumference, body mass, fat mass, height, and %BF. Finally, a high SJIS degree was observed among height and %BF for schoolchildren from rural and urban zones.
CONCLUSION
Brazilian and Mozambican children exhibit differences in growth characteristics but a high degree of similarity when children from rural and urban zones are compared.
背景/目的：巴西和莫桑比克面临相似的社会经济挑战，包括儿童营养不良和营养过剩的常见指标。本研究通过使用杰卡德指数评估巴西和莫桑比克儿童人体测量和身体成分变量的相似程度。
方法
来自巴西三个城市（累西腓、圣安东尼奥维多利亚和卡罗湖）和莫桑比克三个城市（马普托、博阿内和伊尼扬巴内）的1831名7至10岁的男女儿童参与了本研究。测量了人体测量学指标（身高、体重和腰围）和身体成分指标（体脂百分比[%BF]、瘦体重和脂肪量），并使用平滑杰卡德指数曲面（SJIS）评估相似程度。
结果
巴西儿童比莫桑比克儿童更高、更重，且%BF和脂肪量更高。两国城市地区的儿童比农村地区的儿童更高。巴西和莫桑比克儿童仅在%BF和瘦体重之间表现出高度相似性。来自累西腓和马普托的儿童在腰围、体重、脂肪量、身高和%BF方面具有高度相似性。最后，在农村和城市地区的学童中，身高和%BF之间观察到高度的SJIS程度。
结论
巴西和莫桑比克儿童在生长特征上存在差异，但在比较农村和城市地区的儿童时具有高度相似性。
