BACKGROUND
Although global nutrition/dietary transition resulting from industrialisation and urbanisation has been identified as a major contributor to widespread trends of obesity, there is limited data in pregnant women, including those living with HIV in South Africa. We examined food-based dietary intake in pregnant women with and without HIV at first antenatal care (ANC) visit, and associations with maternal overweight/obesity and gestational weight gain (GWG).
METHODS
In an urban South African community, consecutive women living with (n = 479) and without (n = 510) HIV were enrolled and prospectively followed to delivery. Interviewer-administered non-quantitative food frequency questionnaire was used to assess dietary intake (starch, protein, dairy, fruits, vegetables, legumes, oils/fats) at enrolment. Associations with maternal body mass index (BMI) and GWG were examined using logistic regression models.
RESULTS
Among women (median age 29 years, IQR 25-34), the prevalence of obesity (BMI ≥ 30 kg/m) at first ANC was 43% and that of excessive GWG (per IOM guidelines) was 37% overall; HIV prevalence was 48%. In women without HIV, consumption of potato (any preparation) (aOR 1.98, 95% CI 1.02-3.84) and pumpkin/butternut (aOR 2.13, 95% CI 1.29-3.49) for 1-3 days a week increased the odds of overweight/obesity compared to not consuming any; milk in tea/coffee (aOR 6.04, 95% CI 1.37-26.50) increased the odds of excessive GWG. Consumption of eggs (any) (aOR 0.52, 95% CI 0.32-0.86) for 1-3 days a week reduced the odds of overweight/obesity while peanut and nuts consumption for 4-7 days a week reduced the odds (aOR 0.34, 95% CI 0.14-0.80) of excessive GWG. In women with HIV, consumption of milk/yoghurt/maas to drink/on cereals (aOR 0.35, 95% CI 0.18-0.68), tomato (raw/cooked) (aOR 0.50, 95% CI 0.30-0.84), green beans (aOR 0.41, 95% CI 0.20-0.86), mixed vegetables (aOR 0.49, 95% CI 0.29-0.84) and legumes e.g. baked beans, lentils (aOR 0.50, 95% CI 0.28-0.86) for 4-7 days a week reduced the odds of overweight/obesity; tomato (raw/cooked) (aOR 0.48, 95% CI 0.24-0.96) and mixed vegetables (aOR 0.38, 95% CI 0.18-0.78) also reduced the odds of excessive GWG.
CONCLUSIONS
Diet modification may promote healthy weight in pregnant women living with and without HIV.
背景
尽管由于工业化和城市化导致的全球营养/饮食转变已被确定为肥胖广泛流行趋势的主要原因之一，但在南非，患有 HIV 的孕妇的数据有限。我们研究了首次产前保健就诊时患有和不患有 HIV 的孕妇的基于食物的饮食摄入情况，以及这些因素与孕妇超重/肥胖和妊娠体重增加（GWG）之间的关系。
方法
在南非一个城市社区，连续招募了患有（n=479）和不患有（n=510）HIV 的孕妇，并进行前瞻性随访至分娩。使用访谈者管理的非定量食物频率问卷评估登记时的饮食摄入情况（淀粉、蛋白质、乳制品、水果、蔬菜、豆类、油/脂肪）。使用逻辑回归模型检查与母体体重指数（BMI）和 GWG 的关联。
结果
在（中位数年龄 29 岁，IQR 25-34）的女性中，首次 ANC 时肥胖（BMI≥30kg/m）的患病率为 43%，总体上过度 GWG（按 IOM 指南）的患病率为 37%；HIV 患病率为 48%。在没有 HIV 的女性中，每周食用 1-3 天的土豆（任何形式）（OR 1.98，95%CI 1.02-3.84）和南瓜/冬南瓜（OR 2.13，95%CI 1.29-3.49）会增加超重/肥胖的几率，而不食用任何这些食物；每周食用 1-3 天的茶/咖啡中的牛奶（OR 6.04，95%CI 1.37-26.50）会增加过度 GWG 的几率。每周食用 1-3 天鸡蛋（任何形式）（OR 0.52，95%CI 0.32-0.86）会降低超重/肥胖的几率，而每周食用 4-7 天花生和坚果会降低超重/肥胖的几率（OR 0.34，95%CI 0.14-0.80）。在患有 HIV 的女性中，每周食用 1-3 天牛奶/酸奶/马萨（OR 0.35，95%CI 0.18-0.68）、番茄（生/熟）（OR 0.50，95%CI 0.30-0.84）、绿豆（OR 0.41，95%CI 0.20-0.86）、混合蔬菜（OR 0.49，95%CI 0.29-0.84）和豆类，例如烤豆、扁豆（OR 0.50，95%CI 0.28-0.86），每周食用 4-7 天，会降低超重/肥胖的几率；番茄（生/熟）（OR 0.48，95%CI 0.24-0.96）和混合蔬菜（OR 0.38，95%CI 0.18-0.78）也降低了过度 GWG 的几率。
结论
饮食改变可能会促进患有和不患有 HIV 的孕妇保持健康的体重。
