To evaluate daily eating frequency (main meals and snacks) in relation to weight status in children aged 3-9 years, representative of the Portuguese population.
Cross-sectional study. Dietary intake was estimated as the mean of two non-consecutive days of food diaries, followed by face-to-face interviews. Weight and height were measured by trained observers. Eating occasions (EO) were defined by the children's caregiver; an EO was considered separate if the time of consumption was different from other EO and it provided at least 209 kJ (50 kcal). Main meals defined as 'breakfast', 'lunch' and 'dinner' could be selected only once per day. The remaining EO were considered snacks. The association between eating frequency and overweight/obesity was evaluated through logistic regressions weighted for the population distribution.
National Food, Nutrition and Physical Activity Survey of the Portuguese population, 2015-2016.
Portuguese children aged 3-9 years with complete dietary data and anthropometric measurements (n 517).
Overall, the number of daily EO ranged from 3·5 to 11, and on average children had 5·7 daily EO. After adjustment for child's sex, age and total energy intake, and considering only plausible energy intake reporters, having < 3 snacks/d was positively associated with being overweight/obese (OR = 1·98; 95 % CI 1·00, 3·90), compared with having ≥ 3 snacks/d.
Lower daily frequency of EO was associated with increased odds of being overweight or obese in children. A higher eating frequency, maintaining the same energy intake, seems to contribute to a healthy body weight in children.
评估 3-9 岁儿童的日常进食频率(正餐和零食)与体重状况的关系,该研究人群具有葡萄牙代表性。
横断面研究。膳食摄入量通过 2 天非连续的食物日记进行估计,随后进行面对面访谈。由经过培训的观察者测量体重和身高。进食次数(EO)由儿童的照顾者定义;如果消费时间与其他 EO 不同且提供至少 209 kJ(50 kcal),则认为是单独的 EO。正餐定义为“早餐”、“午餐”和“晚餐”,每天只能选择一次。其余的 EO 被认为是零食。通过对人群分布进行加权的逻辑回归评估进食频率与超重/肥胖的关系。
2015-2016 年葡萄牙全国食物、营养和身体活动调查。
具有完整饮食数据和人体测量学测量值的 3-9 岁葡萄牙儿童(n 517)。
总体而言,每日 EO 数量范围为 3.5-11 次,平均儿童每日有 5.7 次 EO。在调整儿童性别、年龄和总能量摄入,并仅考虑合理能量摄入报告者后,与每日食用≥3 次零食相比,每日食用<3 次零食与超重/肥胖呈正相关(OR = 1.98;95 % CI 1.00,3.90)。
较低的每日 EO 频率与儿童超重或肥胖的几率增加有关。更高的进食频率,在保持相同能量摄入的情况下,似乎有助于儿童保持健康的体重。
