目的为了解城乡居民营养状况及体质指数分布趋势,更科学地、简易地指导城乡居民的合理营养,平衡膳食。方法按照全国营养调查方法,采用多阶整群随机抽样方法,按等概率原则在贺州市八步区城乡抽取3个乡镇的6个村委会、共537户。其中膳食调查177户共613人,健康体检2401人。体格测量使用校正过的测量工具,由经过专门培训合格的人员进行测量及质控。结果营养不良率男略高于女性,而超重率则是女性高于男性,但两者之间无差异统计学意义(P>0.05)。肥胖率女性显著高于男性(P<0.01)。60岁以上年龄组营养不良患病率最高,和广西平均水平接近;超重患病率接近广西平均水平;肥胖患病率低于广西平均水平。结论在贺州地区,营养失衡发生率仍然很高,提示开展营养教育,正确引导食物消费,建立合理科学与健康的食物消费观念,控制超重或肥胖,具有十分重要意义。
The purpose is to understand the distribution status of the nutritional status and body mass index of urban and rural residents, and to guide the reasonable nutrition of urban and rural residents more scientifically and easily and to balance the diet. Methods According to the National Nutrition Survey Method, a multi-stage cluster random sampling method was adopted. According to the principle of equal probability, 6 village committees and 537 households in 3 townships were selected in the urban and rural areas of Babu District of Hezhou City. Of these, 177 households had a total of 613 food surveys and 2401 health examinations. Physical measurements use calibrated measurement tools, which are measured and controlled by specially trained personnel. Results Malnutrition rate was slightly higher in males than in females, while overweight was higher in females than males, but there was no significant difference between the two (P>0.05). Obesity was significantly higher in women than in men (P<0.01). The prevalence of malnutrition was highest in the 60+ age group, which was close to the average level in Guangxi; the prevalence of overweight was close to the Guangxi average; the prevalence of obesity was lower than the Guangxi average. Conclusion The prevalence of nutritional imbalance in Hezhou is still high, suggesting that it is of great significance to carry out nutrition education, correctly guide food consumption, establish reasonable scientific and healthy food consumption concepts, and control overweight or obesity.
