目的了解青海省某贫困县农村居民身体活动及相关行为特点。方法对青海省某国家级贫困县2个自然村的18周岁及以上的居民询问蔬菜、水果的消费量,饮酒、吸烟以及业余锻炼、骑车和中速以上步行等身体活动的频率、时间等。结果 908名居民平均每天消费新鲜蔬菜(262.8±182.4)g、水果(44.2±79.9)g、酒精(9.4±23.5)g,现在吸烟率为32.7%。分别有167人(18.4%)、354人(39.0%)和177人(19.5%)骑自行车、中速以上步行和业余锻炼,不同骑车、中速以上步行、业余锻炼频率水平的居民平均每天的新鲜蔬菜和酒精消费量差异均无统计学意义(P>0.05);不同活动时间水平的骑车、中速以上步行者的蔬菜、水果、酒精消费量、现在吸烟率差异均无统计学意义(P>0.05)。每次业余锻炼时间不足30 min者新鲜蔬菜消费量([348.5±279.5)g/d]明显高于不锻炼者([259.7±179.0)g/d]和每次锻炼30~、60~min者[分别为(254.1±177.1)、(257.8±152.0)g/d],差异有统计学意义(P<0.05),每周锻炼5~7次或每次业余锻炼30~60 min者水果消费量[分别为(59.0±83.4)、(61.6±75.1)g/d]均明显高于不锻炼者([40.6±79.5)g/d],差异有统计学意义(P<0.05);每周骑车4~7次者现在吸烟率(27.5%)明显低于每周骑车1~3次者(46.1%),差异有统计学意义(P<0.05)。结论样本人群中参与较多身体活动者可能更倾向于多吃蔬菜水果、戒烟等较为健康的生活方式。
Objective To understand the physical activities and related behaviors of rural residents in a poor county in Qinghai Province. Methods The residents aged 18 years old and above in two villages in a national poverty county of Qinghai Province were asked about the frequency and time of physical activity such as vegetable and fruit consumption, drinking and smoking, and spare time exercise, cycling and walking at medium speed and above. Results On average, 908 residents consumed 262.8 ± 182.4 g of fresh vegetables per day, 44.2 ± 79.9 g of fruits and 9.4 ± 23.5 g of alcohol. The current smoking rate was 32.7%. Respectively, 167 (18.4%), 354 (39.0%) and 177 (19.5%) ride bicycles, and walk and amateur exercises at medium speed. Residents of different cyclists and middle-speed walking and part- There was no significant difference in the consumption of fresh vegetables and alcohol (P> 0.05). There was no significant difference in the current consumption rates of vegetables, fruits and alcohol among the cyclists (P> 0.05). The consumption of fresh vegetables ([348.5 ± 279.5] g / d] was significantly higher than that of non-exercisers ([259.7 ± 179.0] g / d] and exercise time of 30 ~ 60 min [(254.1 ± 177.1) and (257.8 ± 152.0) g / d, respectively, with significant difference (P <0.05), fruit consumption of 5-7 times a week or 30-60 minutes of each amateur exercise (59.0 ± 83.4 and 61.6 ± 75.1 g / d, respectively) were significantly higher than those who did not exercise ([40.6 ± 79.5] g / d], the difference was statistically significant (P <0.05) The smoking rate (27.5%) was significantly lower in those who were 4 ~ 7 times than those who drove 1 ~ 3 times a week (46.1%), the difference was statistically significant (P <0.05). Conclusions Participants in the sample population who are engaged in more physical activity may be more likely to eat more healthy fruits and vegetables, fruits and smoking cessation and other healthier lifestyles.
