背景和目标 之前的一项试点研究揭示了城市化定居藏族社区中存在发育迟缓的儿童和肥胖的成年人。对选定社区的代表性人口进行了一项调查，以检验初步结果。方法和研究设计 在社区中对 504 名儿童（244 名男孩和 260 名女孩，5-16 岁）和 927 名成人（422 名男性和 505 名女性，18-90 岁）进行了营养状况横断面研究，并测量了人体测量参数。儿童年龄别身高 (HAZ) 和年龄别体重指数 (BAZ) 的 z 分数根据 WHO 2007 年参考值计算。结果 儿童表现出营养不足和营养过剩的双重负担。儿童营养不良的患病率很高 - 发育迟缓（HAZ 2）。 HAZ的平均值（- 0.45±1.41）低于WHO参考值，而BAZ的平均值（0.05±1.76）与WHO参考值相当。性别之间营养不足或过度的情况没有发现显着差异。具体来说，8.9% 的儿童表现出身材矮小（HAZ 1）。相比之下，社区成年人几乎呈现出一种单向的营养过剩倾向——超重61.4%（BMI≥24kg/m2），肥胖30.1%（BMI≥28kg/m2），中心性肥胖62.0%（腰围，男性≥85cm，女性≥80cm）。女性肥胖的可能性略高于男性（p=0.061）。结论 社区营养不足和营养过剩的共存可能反映了生命早期营养不良和后来的肥胖环境。需要探索未来干预措施的潜在决定因素。
BACKGROUND AND OBJECTIVES A previous pilot study revealed stunted children and obese adults in urbanized settled Tibetan communities. A survey with a representative population in selected communities was conducted to test the preliminary findings. METHODS AND STUDY DESIGN A cross-sectional study on the nutritional status involving 504 children (244 boys and 260 girls, 5-16 y) and 927 adults (422 men and 505 women, 18-90 y) was conducted in communities, with anthropometric parameters measured. The z-scores for height-for-age (HAZ) and BMI-for-age (BAZ) in children were calculated according to WHO 2007 reference. RESULTS The children showed a double burden of both under- and over-nutrition. The prevalence of under-nutrition in children was high - stunting (HAZ 2). The mean value of HAZ (- 0.45±1.41) was lower than, whereas that of BAZ (0.05±1.76) was comparable to, the WHO reference. No significant differences were found in under- or over-nutrition between genders. Specifically, 8.9% of children demonstrated both short stature (HAZ 1). By contrast, community adults showed almost a one-way direction tilted towards over-nutrition - overweight 61.4% (BMI ≥24 kg/m2), obesity 30.1% (BMI ≥28 kg/m2), and central obesity 62.0% (waist circumference, men ≥85 cm, women ≥80 cm). Women were marginally more likely to be obese than men (p=0.061). CONCLUSIONS The co-existence of under- and over-nutrition in the community may have reflected the suboptimal early life nutrition and the obesogenic environment afterwards. Potential determinants need to be explored for future interventions.
