The prevalence of lack of physical activity in males was 74.87% higher than that in females (69.44%), the difference was statistically significant (P <0.01 ) In rural areas (90.52%) than in urban areas (35.02%), the difference was statistically significant (P <0.01). The standardization rates of not eating on time and not eating on time were 41.67% and 35.42% respectively in the surveyed population, 42.76% in male and 40.86% in female, and 35.91% in female when not eating (34.75%); rural residents do not eat on time, do not eat breakfast on time (53.21%, 45.97%) than the city (18.02%, 14.35%); staple food intake of rice (99.95%) mainly meat Pigs, cattle and mutton (82.68%) were the mainstay, with the lowest recurrent rate of 2.14% in rural dairy and dairy products.
