目的了解石家庄市事业单位轻体力劳动成年人能量摄入量状况。方法在石家庄市某事业单位选择三餐在食堂用餐的处于轻体力活动水平的38名成年人作为调查对象。采用称重记录法调查其每日的膳食种类及摄入量,并通过查阅食物成分表计算每日的能量摄入量。结果每日能量摄入量男性为(9070.0±1497.5)kJ[(2167.9±357.9)kcal)],女性为(7669.9±1396.5)kJ[(1833.2±333.8)kcal)]。以公斤体重计算,男性组为(130.9±17.4)kJ/(kg.d),女性组为(139.0±25.8)kJ/(kg.d)。男女的每日能量摄入量均比我国2000年制定的轻体力活动成年人的RNI值低。此外,受试对象全天各餐之间摄能比分别为早餐18.6%、中餐41.5%、晚餐35.0%,其中早餐摄能比值偏低。结论中国轻体力劳动成年人能量摄入的RNI值可能偏高,在评价能量摄入量时应考虑体重因素的影响。
Objective To understand the energy intake status of adults with light manual labor in institutions in Shijiazhuang City. Methods A total of 38 adults who were at light stamina in the dining hall at a certain institution in Shijiazhuang City were selected as the survey subjects. Weighing records were used to investigate daily dietary intake and dietary intake, and daily energy intake was calculated by consulting the food composition table. Results Daily energy intake of male (9070.0 ± 1497.5) kJ [(2167.9 ± 357.9) kcal)], female (7669.9 ± 1396.5) kJ [(1833.2 ± 333.8) kcal)]. In kg body weight, the male group was (130.9 ± 17.4) kJ / (kg.d) and the female group was (139.0 ± 25.8) kJ / (kg.d). The daily energy intake of both men and women is lower than the RNI of adults with light physical activity in 2000. In addition, the subjects were able to take 18.6% of breakfasts, 41.5% of meals and 35.0% of supper respectively during the whole day. The ratio of breakfast energy intake was low. Conclusion The RNI of energy intake of adults with light manual labor in China may be high, and the influence of body weight should be considered when assessing energy intake.
