[Status of discomfort response and major impact factors among children aged 6-24 months in poor rural areas of Hunan Province in 2015].

Objective: To understand the status and related factors of the discomfort reaction of 6-24 month old infants in poor rural areas of Hunan Province.

Methods: In 2015, 7481 rural infants aged from 6 to 24 month old in rural areas were collected from 25 poor counties in Hunan Province by probability proportional sampling(PPS) and systematic sampling method. A questionnaire was designed to survey the basic information of infants, feeding mode of nutrition package and the discomfort reaction, etc. And the multivariate non-conditional logistic regression model was used to analyze the status and related factors of discomfort reactions in infants aged 6-24 months.

Results: The infant nutrition package offering rate was 90.9%(6799/7481), and the effective taking rate was 69.2%(4707/6799). And 54.3%(3695/6799) infants did not insist on eating nutrition pack everyday. The discomfort rate was 10.6%(719/6799), accounting for 9.6%(719/7481) of the total number in the survey. The difference of response to infant nutrition packs in different age groups was statistically significant(χ~2=9.330, P=0.009). With the increase of age, the discomfort reaction rate of nutritional packs showed a decreasing trend. There was a statistically significant difference(P<0.05) in the discomfort response rate with the different age groups, nationalities, manufacturers, preterm infants and fever or diarrhea among infants. 35.9% of caregivers stopped feeding nutritious packages to infants after the discomfort reaction, while only 16.0% of caregivers insisted on feeding nutritious packages for infants. 24.7%(1677/6799) of the main caregivers knew knowledge of nutrition package, 6.5%(444/6799) of the caregivers had no knowledge of nutrition package. 85.4% of caregivers had obtained nutrition package knowledge by rural doctors. Less than 10% had access to nutrition packs via television or radio.

Conclusion: In poor rural areas of Hunan Province, discomfort reaction rate of infant nutrition package taking is high. Different ages, nationalities, manufacturers, whether in preterm infants, have a fever and diarrhea are the influencing factors of infant nutrition package taking discomfort. Caregivers awareness of nutritional package knowledge is relatively low.
