BACKGROUND
Maternal stature and body mass indices (BMI) of non-pregnant women (NPW) of child bearing age are relevant to maternal and offspring health. The objective was to compare anthropometric indices of NPW in four rural communities in low- to low-middle income countries (LMIC).
METHODS
Anthropometry and maternal characteristics/household wealth questionnaires were obtained for NPW enrolled in the Women First Preconception Maternal Nutrition Trial. Body mass index (BMI, kg/m) was calculated. Z-scores were determined using WHO reference data.
RESULTS
A total of 7268 NPW participated in Equateur, DRC (n = 1741); Chimaltenango, Guatemala (n = 1695); North Karnataka, India (n = 1823); and Thatta, Sindh, Pakistan (n = 2009). Mean age was 23 y and mean parity 1.5. Median (P25-P75) height (cm) ranged from 145.5 (142.2-148.9) in Guatemala to 156.0 (152.0-160.0) in DRC. Median weight (kg) ranged from 44.7 (39.9-50.3) in India to 52.7 (46.9-59.8) in Guatemala. Median BMI ranged from 19.4 (17.6-21.9) in India to 24.9 (22.3-28.0) in Guatemala. Percent stunted (<-2SD height for age z-score) ranged from 13.9% in DRC to 80.5% in Guatemala; % underweight (BMI <18.5) ranged from 1.2% in Guatemala to 37.1% in India; % overweight/obese (OW, BMI ≥25.0) ranged from 5.7% in DRC to 49.3% in Guatemala. For all sites, indicators for higher SES and higher age were associated with BMI. Lower SES women were underweight more frequently and higher SES women were OW more frequently at all sites. Younger women tended to be underweight, while older women tended to be OW.
CONCLUSIONS
Anthropometric data for NPW varied widely among low-income rural populations in four countries located on three different continents. Global comparisons of anthropometric measurements across sites using standard reference data serve to highlight major differences among populations of low-income rural NPW and assist in evaluating the rationale for and the design of optimal intervention trials.
TRIAL REGISTRATION
ClinicalTrials.gov # NCT01883193 (18 June 2013, retrospectively registered).
背景
育龄非孕妇（NPW）的母亲身高和体重指数（BMI）与母婴健康相关。目的是比较低收入至中低收入国家（LMIC）四个农村社区中NPW的人体测量指标。
方法
对参与“女性孕前孕产妇营养试验”的NPW进行人体测量，并发放母亲特征/家庭财富问卷。计算体重指数（BMI，kg/m）。使用世界卫生组织参考数据确定Z评分。
结果
共有7268名NPW参与研究，其中刚果民主共和国赤道省（n = 1741）；危地马拉奇马尔特南戈（n = 1695）；印度北卡纳塔克邦（n = 1823）；巴基斯坦信德省塔塔（n = 2009）。平均年龄为23岁，平均产次为1.5次。身高中位数（P25 - P75，cm）范围从危地马拉的145.5（142.2 - 148.9）到刚果民主共和国的156.0（152.0 - 160.0）。体重中位数（kg）范围从印度的44.7（39.9 - 50.3）到危地马拉的52.7（46.9 - 59.8）。BMI中位数范围从印度的19.4（17.6 - 21.9）到危地马拉的24.9（22.3 - 28.0）。发育迟缓百分比（年龄别身高Z评分＜ - 2SD）范围从刚果民主共和国的13.9%到危地马拉的80.5%；体重过轻百分比（BMI＜18.5）范围从危地马拉的1.2%到印度的37.1%；超重/肥胖百分比（OW，BMI≥25.0）范围从刚果民主共和国的5.7%到危地马拉的49.3%。在所有研究地点，较高社会经济地位（SES）和较高年龄的指标与BMI相关。较低SES的女性体重过轻更为常见，而较高SES的女性超重更为常见。年轻女性往往体重过轻，而年长女性往往超重。
结论
位于三个不同大陆的四个国家低收入农村人口中NPW的人体测量数据差异很大。使用标准参考数据对各地点人体测量指标进行全球比较，有助于突出低收入农村NPW人群之间的主要差异，并协助评估最佳干预试验的基本原理和设计。
