摘要
目的分析九省区18-49岁居民能量摄入状况及其变化趋势,为中国居民能量参考摄入量修订和相应的膳食指导提供依据。方法以"中国健康与营养调查"项目1989-2009年间8次调查中有膳食调查资料的18-49岁调查对象作为研究对象。使用SAS9.2软件对数据库资料进行统计分析。结果 2009年九省区18-49岁男女性成年居民的能量摄入[kJ/d(kcal/d)]分别为10277.6(2456.4)和8539.1(2040.9)。其中城市、郊区、县城和农村男性成年居民的能量摄入[kJ/d(kcal/d)]分别为9707.3(2320.1),10022.8(2395.5),9876.3(2360.5)和10632.8(2541.3);女性分别为7923.7(1893.8),8120.7(1940.9),8340.0(1993.3)和8909.0(2129.3)。能量的食物来源以谷类食物为主,尤其是农村成年居民,约占总能量的57.7%。蛋白质、脂肪和碳水化合物供能比分别为15.1%、31.4%和53.5%。其中,城市、郊区、县城和农村成年居民的脂肪供能比分别为36.0%、33.7%、32.19%和29.2%,1989-2009年我国成年居民能量摄入呈现出总体下降的趋势,能量摄入从高到低依次为农村、郊区、县城、城市,以郊区降低最明显,20年间减少1966.1 kJ/d(469.9 kcal/d)。结论 2009年我国九省区18-49岁成年居民能量摄入较前有较大幅度减少,脂肪供能比显著增加,使肥胖及膳食相关慢性病的高危人群增加。其原因可能在于动物性食物和食用油摄入的增加,值得重点关注。在修订能量参考摄入量和制订膳食指导原则时,应充分考虑我国的经济发展水平及不同地区的人群膳食消费特点。
Objective To identify the trends of energy intake among Chinese adults in 9 provinces from 1989 to 2009.Method The adults aged 18-49 years with three days 24 h dietary recall data from China Health and Nutrition Survey（1989,1991,1993,1997,2000,2004,2006 and 2009） were selected as subjects studied.The current situation and long-term trends in energy intake were analyzed through SAS software.Results The average energy intake of Chinese adults aged 18-49 years in 2009 was 10278 kJ/d（2456 kcal/d） in males and 8539 kJ/d（2040.9 kcal/d） in females.Whereas the energy intake in the adults in city,suburb,town and village was 9707.3,10022.8,9876,10632.8 kJ/d（2320,2395.5,2360.5,2541.3 kcal/d） in men and 7923.7,8120.7,8340.0,8909.0 kJ/d（1893.8,1940.9,1993.3,2129.3 kcal/d） in women respectively.Cereal was the main food source of energy intake,accounted for 57.7% of total energy intake in rural adults.The percentage of energy intake from dietary protein,fats and carbohydrate was 15.1%,31.4% and 53.5% respectively.The average percentage of energy consumption from fats in the adults in city,suburb,town and village was 36.0%,33.7%,32.1% and 29.2% respectively.A decline trend in energy intake could be seen from 1989 to 2009.The average energy intake of four area groups from high to low was village,suburb,town and city.The biggest decline was in suburb group,about 1966 kJ/d（469.9 kcal/d） from 1989 to 2009.Conclusion The energy intake of Chinese adult aged 18-49 years decreased substantially in 2009.There was significant increase in percentage of energy intake from fat due to increased consumption of animal foods and edible oil during the past 20 years.Excess fat intake could result in higher risk of dietary related chronic diseases.We have to pay more attention to economic development level and food consumption habit in revising Chinese DRIs and formulating specific dietary guideline.
