[Relationship Between Maternal Negative Emotions and Feeding Patterns of Infants Aged 0-6 Months in Remote Rural Areas of Sichuan Province].

Objective To investigate the status of exclusive breastfeeding and bottle feeding in remote rural areas of Sichuan province and explore the relationship between negative emotions of mothers and feeding patterns of infants.Methods Multistage cluster sampling was employed to select the infants aged 0-6 months and their mothers in remote rural areas of Sichuan province.A self-designed questionnaire was used to collect the demographic characteristics of mothers and infants and the basic family information.The Chinese version of Depression Anxiety Stress scale was used to evaluate mothers' negative emotions,and the Breastfeeding Self-efficacy scale to assess the confidence level of mothers' behavior of adhering to exclusive breastfeeding.Results Totally 723 pairs of infants and their mothers were included.The exclusive breastfeeding and bottle feeding rates were 34.16% (247/723) and 57.54% (416/723),respectively.Mothers with depression tendency were less likely to adopt exclusive breastfeeding (OR=0.532,95%CI=0.291-0.974,P=0.041) and more likely to adopt bottle feeding (OR=1.877,95%CI=1.054-3.344,P=0.033).Further subgroup analysis of breastfeeding self-efficacy showed that in the group of low self-efficacy,the mothers with depression tendency were less likely to adopt exclusive breastfeeding (OR=0.461,95%CI=0.236-0.902,P=0.024) and more likely to adopt bottle feeding (OR=1.968,95%CI=1.047-3.701,P=0.036) than the mothers without depression tendency.In the group of high self-efficacy,mothers' depression,anxiety,and stress tendency had no significant correlation with infant feeding patterns (all P>0.05).Conclusions The mothers in the remote rural areas of Sichuan province are more likely to employ bottle feeding than exclusive breastfeeding.The mothers with stronger depression tendency demonstrate lower possibility of exclusive breastfeeding and higher possibility of bottle feeding.Breastfeeding self-efficacy may affect the association between maternal depression and infant feeding patterns.

[Current Situation and Influencing Factors of Delay in Seeking Medical Treatment Among Residents in Rural Areas of Sichuan Province].

Objective To understand the current situation and explore the influencing factors of delay in seeking medical treatment for common symptoms of residents in the rural areas of Sichuan province. Methods In July 2019,multi-stage random sampling was carried out in Zigong city,Sichuan province,and the data were collected by face-to-face questionnaire interview.The residents who had lived at hometown for more than half a year in the past year and had seen a doctor in the most recent month were surveyed.Logistic regression was adopted to predict the influencing factors of delay in seeking medical treatment. Results A total of 342 subjects were enrolled,and the incidence of delay in seeking medical treatment was 13.45%(46/342).Compared with the young and middle-aged(<65 years)people,the elderly(≥65 years)people were more likely to have delay in seeking medical treatment (OR=2.187,95%CI=1.074-4.457,P=0.031).The rural residents who gave higher score of the overall quality of township health centers were less likely to have delay in seeking medical treatment (OR=0.854,95%CI=0.735-0.992,P=0.039). Conclusions The occurrence of delay in seeking medical treatment for common symptoms of rural residents in Sichuan province is low.Age and the overall quality evaluation of township health centers affect the occurrence of delay in medical treatment among the rural residents in Sichuan province.Efforts should be made to improve the awareness of disease prevention among the elderly in rural areas.The investment in health resources in township health centers should be increased to strengthen the introduction and training of talents.These measures can improve the health services in township health centers,guide residents to make timely use of health resources,and reduce the occurrence of delay in seeking medical treatment.

[Association of Dietary Diversity with Growth and Development of Children in Multi-ethnic Rural Areas of Sichuan Province].

Objective To understand the growth and dietary diversity status of children in multi-ethnic areas of Sichuan province,and to explore the associations of dietary diversity with growth and development indicators. Methods Children of 18-36 months old and their primary caregivers were selected with multi-stage cluster random sampling method from rural areas of Han,Tibetan,and Yi ethnic groups in Sichuan province. The sociodemographic information of children and their caregivers was collected using self-designed questionnaire.The dietary diversity score(DDS)was calculated according to the criteria in the Guidelines for Measuring Household and Individual Dietary Diversity released by the Food and Agriculture Organization of the United Nations.The body height(length)and body weight of each child were measured by standard equipment for anthropological measurement,and the height for age Z score(HAZ),weight for age Z score(WAZ),and weight for height Z score(WHZ) were calculated.Multivariate linear regression was performed to analyze the relationship between dietary diversity and growth indicators of children. Results A total of 1092 children were enrolled in this study,and the prevalence of stunting(HAZ<-2),underweight(WAZ<-2),and wasting(WHZ<-2)was 21.1%,4.9%,and 2.5%,respectively.The children had the mean DDS of 4.8±1.7,and 45.3% of children had poor dietary diversity(DDS≤4).The children of Han ethnic group(5.8±1.4)had higher DDS than those of Tibetan ethnic group(4.9±1.6)and Yi ethnic group(3.9±1.6)(P<0.001).The results of multivariate linear regression indicated that DDS was positively correlated with HAZ(ß=0.206,95%CI=0.158-0.254,P<0.001)after adjustment of sex,age,birth weight,preterm birth,and parental body height.After further adjustment of family fixed assets,ethnic group,caregiver's type,and caregiver's education background,the correlation between DDS and HAZ remained significant(ß=0.077,95%CI=0.026-0.128, P=0.003). Conclusions The children in the multi-ethnic rural areas of Sichuan province showed troublesome growth and development status and low dietary diversity,which were conspicuously different between ethnic groups,especially in the rural areas of Yi ethnic group.The dietary diversity was positively associated with HAZ.It is recommended to carry out nutrition and health education according to the local dietary characteristics and thus improve the growth and development of children in multi-ethnic rural areas in Sichuan.
