Abstract

Background: People with intellectual disabilities (IDs) have an increased risk of obesity and health concerns related to their nutritional status and dietary intake.

Objective: To assess the effectiveness of a multi-component intervention on weight, waist circumference (WC), clinical health parameters and dietary habits in a group of overweight and obese adults with mild-to-moderate ID.

Design: A 7-month cluster-randomised trial and a 7-month follow-up of the intervention group after the end of intervention when the group received usual care. The intervention consisted of monthly dietary-group courses tailored to the participants’ cognitive abilities and practical skills, monthly nutritional courses for staff, use of behaviour change techniques and nudging. The control group received usual care during the intervention.

Results: There were 32 participants aged 22–61 years: 15 in the intervention group and 17 in the control group. After 7 months, a non-significant weight difference (median difference = −1.25 kg; 95% confidence interval [CI] = −2.00; 0.95 vs. +1.00 kg; CI = −1.15; 3.00, P = 0.08) and a significant WC difference were observed between the intervention and control groups (median difference = −3.75 cm; CI: −7.68; 0.11 vs. 0 cm; CI = −3.99; 1.00, P = 0.03), respectively. The median reduction in WC continued in the intervention group during the 7-month follow-up (median difference = −7.50 cm; CI: −13.57; −3.16, P = 0.002). A significant difference in frequency intake of fruit (P = 0.03) and berries (P = 0.004) was observed between the groups after 7 months, supported by a significant increase in measured serum-carotenoid levels in the intervention group after 7 months (median difference = 0.26 mmol/L; CI: −0.12; 0.52, P = 0.007).

Conclusions: A significant difference in WC was observed between the groups, accompanied by changes in blood parameters and dietary habits.

针对智障成人的分组随机对照试验中的体重减轻和饮食改善情况

背景：智障人士（IDs）肥胖的风险增加，他们的健康问题与营养状况和饮食摄入有关。目的：评估多组分干预措施对轻度至中度智障的超重和肥胖成年人的体重、腰围、临床健康参数和饮食习惯的影响。设计：为期 7 个月的分组随机试验，在干预结束后对干预组进行为期 7 个月的随访，干预组接受常规护理。干预措施包括根据参与者的认知能力和实际技能定制每月饮食小组课程、为员工提供每月营养课程、使用行为改变技术和暗示。对照组在干预期间接受常规护理。结果：32 名参与者的年龄在 22-61 岁之间：干预组 15 人，对照组 17 人。7 个月后，观察到干预组和对照组的体重差异不显著（中位数差异 = -1.25 kg; 95% 置信区间 [CI] = -2.00; 0.95 vs. +1.00 kg; CI = -1.15; 3.00, P =0.08），而腹围差异显著（中位数差异 = -3.75 cm; CI：-0 cm; CI = -3.99; 1.00, P = 0.03）。在 7 个月的随访中，干预组的腹围中位数继续下降（中位数差异 = -7.50 厘米；CI: -13.57; -3.16, P = 0.002）。7 个月后，观察到两组之间水果（P = 0.03）和浆果（P = 0.004）的摄入频率存在明显差异，7 个月后，干预组的血清类胡萝卜素水平也有明显增加（中位数差异 = 0.26 mmol/L；CI：-0.12；0.52, P = 0.007）。结论：观察到干预组之间的体重增加有显著差异，同时血液参数和饮食习惯也发生了变化。

期刊介绍： Food & Nutrition Research is a peer-reviewed journal that presents the latest scientific research in various fields focusing on human nutrition. The journal publishes both quantitative and qualitative research papers. Through an Open Access publishing model, Food & Nutrition Research opens an important forum for researchers from academic and private arenas to exchange the latest results from research on human nutrition in a broad sense, both original papers and reviews, including: * Associations and effects of foods and nutrients on health * Dietary patterns and health * Molecular nutrition * Health claims on foods * Nutrition and cognitive functions * Nutritional effects of food composition and processing * Nutrition in developing countries * Animal and in vitro models with clear relevance for human nutrition * Nutrition and the Environment * Food and Nutrition Education * Nutrition and Economics Research papers on food chemistry (focus on chemical composition and analysis of foods) are generally not considered eligible, unless the results have a clear impact on human nutrition. The journal focuses on the different aspects of nutrition for people involved in nutrition research such as Dentists, Dieticians, Medical doctors, Nutritionists, Teachers, Journalists and Manufacturers in the food and pharmaceutical industries.
