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.
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.
The children showed a double burden of both under- and over-nutrition. The prevalence of under-nutrition in children was high - stunting (HAZ <-2) 10.7%, underweight (BAZ <-2) 9.5%, combined prevalence of stunting and underweight 19.4%. The rate of over-nutrition was also alarming - obesity 12.7% (BAZ >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) and overweight (BAZ >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).
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.
先前的一项试点研究揭示了城市化定居藏区社区中存在发育迟缓的儿童和肥胖的成年人。在选定的社区中进行了一项具有代表性人群的调查，以检验初步发现。
对涉及 504 名儿童（244 名男孩和 260 名女孩，5-16 岁）和 927 名成年人（422 名男性和 505 名女性，18-90 岁）的营养状况进行了横断面研究，测量了人体测量参数。根据世界卫生组织 2007 年的参考标准，计算了儿童身高年龄（HAZ）和体重年龄（BAZ）的 z 分数。
儿童表现出营养不良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）为 10.7%，体重不足（BAZ <-2）为 9.5%，发育迟缓与体重不足的综合患病率为 19.4%。营养过剩的比率也令人担忧 - 肥胖症为 12.7%（BAZ >2）。HAZ 的平均值（-0.45±1.41）低于世界卫生组织的参考值，而 BAZ 的平均值（0.05±1.76）与之相当。性别之间在营养不良或营养过剩方面没有发现显著差异。具体来说，8.9%的儿童同时存在身材矮小（HAZ <-1）和超重（BAZ >1）。相比之下，社区成年人几乎呈现出营养过剩的单一趋势 - 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）。
社区中营养不良和营养过剩的共存可能反映了早期生活营养的不足和后来的肥胖环境。需要探索潜在的决定因素，以进行未来的干预。
