OBJECTIVETo investigate sex difference on nutritional status, feeding practice and health care of rural children in western China.

METHODSData used in this study was from a large scale cross-sectional survey conducted in western rural areas of China. The total number of children younger than 3 years old was 14 532, in which 57.4% were boys. Logistic regression model was employed to control selected background factors for analysis of sex differential on nutritional status,feeding practice and health care of children.

RESULTSThe prevalence rates of stunting, underweight and wasting were close between both genders, regardless of north or south areas. After controlling of selected background factors, sex differentials in malnutrition happened only in north areas. It showed that boys having higher risk of being underweight than girls (OR = 1.27) in the families with one child and lower risk of being stunting than girls ( OR = 0.60). There was no sex differential found in stunting, underweight and wasting for any type of families in south areas. As for feeding practice egg was introduced to boys more frequently compared with girls,which was found in families with one child of south areas and ones with two children from the southern areas. More boys from families with two children of southern areas were exclusively breastfed within 4 months after birth. Data indicated boys had higher risk of being sick. Prevalence of anemia was 36.2% for boys,33.4% for girls. Prevalence of cold was 29.0% for boys,27.4% for girls. Prevalence of diarrhea was 19.0% for boys, 17.5% for girls. This sex differential persisted in the families of north areas after controlling for selected background factors.

CONCLUSIONSex differentials on nutritional status, feeding practice and health care exist in rural areas of western China, especially in north areas.

OBJECTIVETo study the hemoglobin status of children under the age of three years and the prevalence of anemia at high altitude.

METHODSCross-sectional study and randomly sampling were used. Blood was collected on tip of finger and the level of hemoglobin was measured using B-Hemoglobin photometer. We adjusted the hemoglobin based on altitude, using three methods of CDC, Direen's and Dallman's and then estimated the prevalence of anemia.

RESULTS(1) 1 127 children were examined. The findings indicated that the average hemoglobin was about 120 g/L. There was no significant difference for Hb between boys and girls. Urban children had a higher hemoglobin level (123.3 g/L) than rural children (119.9 g/L). Analysis of covariance indicated that, after controlling the factor of altitude, the mean content of hemoglobin of rural children was lower than that of urban children and hemoglobin varied among districts. (2) Different method used for correction of hemoglobin caused different prevalence rates of anemia but they were higher than un-corrected prevalences: 90.4% for CDC method, 72.3% for Dirren's method and 65.0% for Dallman's method respectively.

CONCLUSIONHigher altitude seemed to affect the levels of hemoglobin significantly. The prevalence of anemia in children might be higher, but current hemoglobin correction methods might not be suitable for correcting hemoglobin of Tibetan children. So we suggested that it was imperative to establish a relationship between altitude and hemoglobin of Tibetan children.

OBJECTIVETo investigate optimistic factors affecting nutrition status of infants under 3-year-old in rural areas of western China.

METHODSThe data used in this study came from a cross-sectional survey on primary health and maternal and child health care in western rural China. The method of stratified multistage cluster random sampling was used to obtain the sample of children. Composite index of anthropometric failure (CIAF) was used to classify the infants with normal nutrition or malnutrition. Logistic regression model was employed to investigate optimistic factors effecting nutrition of infants from 3 levels as family, mother and children themselves.

RESULTS14,532 qualified infants were obtained, 57.4% of them were boys. According to CIAF, 72.1% of children were found in normal nutritional status. Prevalence of malnutrition was 27.9% and 10.3% of children were both underweighted and retarded in growth. The result showed the children with better nutrition were from such families with high income, fathers with higher education and fewer children. Higher education for mothers and breastfeeding were optimistic factors effecting nutrition of infants under 6-month after family factors being controlled for. For children over 6 months old, the optimistic factors were heavy mother body weight and more education acquired, exclusive breast feeding within 4-month, introduction of foods containing more protein.

CONCLUSIONFamily factors strongly influence nutritional status of rural children. Improving mothers'education and adding protein intake for children older than 6 months make their nutrition status better.

OBJECTIVETo study the status of spontaneous abortion among reproductive Tibetan women aged 15 - 49 years.

METHODSA cross-sectional survey was conducted on reproductive history of Tibetan women and the sample was chosen under the stratified multistage cluster random sampling technique.

RESULTSA total number of 3741 women were studied with a total number of 10,245 pregnancies. There were 386 spontaneous abortions reported with an incidence rate of 3.9%. Women living in the urban area had a higher rate than living in the rural areas. Women living in area where altitudes were above 4500 m, had a 2-time risk of having spontaneous abortion than those living in areas below 3500 m. The risk of having spontaneous abortion increased among women aged > or = 35 and those with more than 3 pregnancies.

CONCLUSIONSHigh altitude could contribute to the increase of spontaneous abortions incidence, suggesting that improvement of maternal care and nutrition and reduction of the frequency of pregnancy had important roles to play in reducing the incidence of spontaneous abortion among Tibetan women. Despite the fact that retrospective study on reproductive history could underestimate the incidence of spontaneous abortion, the incidence rate among Tibetan women might not be much higher than women living in the lowland areas.

OBJECTIVETo understand the feeding status of Tibetan children aged below three years old.

METHODSCross-sectional study and randomly sampling were used. The information on complementary food was obtained through the recollection from mother of the child. Data of complementary food of Tibet children was compared with those of the children from the surveys of nine cities in China and 40 poor counties in western China.

RESULTSOne thousand six hundred and fifty-five children were studied. The findings indicated that the age of introduction of Zanba (a kind food of mixture of highland barley flour and butter) was 1.98 months after birth and the age of introduction of egg and meat was about 8 - 9 months. Boys were fed with Zanba earlier than girls but there was no significant difference in the introduction of other complementary food between sexes. Urban children were introduced with complementary food earlier than rural children, and children in the agricultural region earlier than those in the pasturing region. The proportion of no introduction of any complementary food by the age of 4 months was about 10.6% for urban children, but 21.7% for rural children while 14.2% for children in the agricultural region and 30.9% for children in the pasturing region. The proportion of no introduction of complementary food was 11.5% for Tibetan children compared with 45.2% for the children of 40 poor counties in western China. The proportions of introduction of the following complementary foods were 89.1% for Zanba, 22.1% for egg, 29.1% for fresh milk, 23.5% for meat, 17.5% for vegetable, 0.75% for bean products, 1.03% for fish and 3.35% for chicken respectively.

CONCLUSIONSThe main complementary foods for Tibetan children included Zanba, milk, mutton and beef. There was a small amount of vegetable in diet. The introduction of bean, chicken and fish was not common. Early and monotony seemed to be the character of introduction of complementary food for Tibetan children. Improving introduction of complementary food is important in enhancing the nutritional status of Tibetan children.

OBJECTIVETo understand the prevalence of anemia in children living in poor rural villages in western China and to find out related factors affecting hemoglobin level of children so as to search for proper intervention.

METHODS3747 children under 3 years old and their families were studied using stratified random sampling in 40 counties in western China. Databases were set up, and data logically checked by Epi 6.0 software. All the data were input with duplication method and analyzed by SPSS 10.0 software.

RESULTSThe prevalence of anemia of children under 3-year-old was 32.7% in 40 counties with significant difference among provinces with the highest in Guizhou province (43.5%). The lowest was in Ningxia and Qinghai provinces, which was 20%. The prevalence of anemia of children was relatively high in 6 and 18 months of age after birth, but declining when children grew older. Many factors were associated with children's anemia, viz. feeding pattern, age, diarrhea, family income, nationality, mother with anemia and drinking clean water etc.

CONCLUSIONInterventions as popularizing knowledge of appropriate feeding, drinking clean water and decreasing the prevalence of common diseases including diarrhea would decrease the prevalence of anemia of local children.

OBJECTIVETo understand the current situation of maternal health care and the association between maternal health care and relevant factors.

METHODSAccording to a cross sectional study design, 1512 mothers having children under 3 years old were drawn under stratified random sampling method and interviewed at their households in 15 counties, Tibet Autonomous Region of China.

RESULTS77.6% of the pregnant women received at least one antenatal checkup with an average of 3.89 times while the rate of antenatal checkup over 5 times was 26.3%. The hospital delivery rate was 40.4% in this area. 83.9% of the women received education under the health care program during pregnancy and 66.2% of them were visited by health workers after delivery. Major factors of the antenatal checkups would include the resource of income, living in nomadic area, personal sanitation, antenatal health care education, mobilization of delivery at hospital, knowledge of antenatal health care etc.

CONCLUSIONSThere had been great improvement in women's health care in this area as compared with the status in 1999, but the frequency of receiving antenatal checkup was still not enough and the rate of hospital delivery was also low as compared with 46 counties in western areas of China. Poor knowledge of health care during pregnancy seemed to be the major factor that limited the utilization of antenatal health care. Knowledge on health and common sense of health care should be disseminated to improve the antenatal care and to enhance the hospital delivery rate.

BACKGROUNDBreast cancer remains the most important cancer among women worldwide. The disease itself and treatment may have a profound impact on the patients' psychological well being and quality of life. Depression is common in breast cancer patients and affects the therapeutic effects as well as prolongs the duration of hospital stay. However, few studies reported the effectiveness of music therapy on depression and duration of hospital stay of female patients with breast cancer after radical mastectomy.

METHODSOne hundred and twenty subjects were recruited to this clinical trial and randomly allocated to two groups. The experimental group (n = 60) received music therapy on the basis of routine nursing care, whereas the control group (n = 60) only received the routine nursing care. The whole intervention time was from the first day after radical mastectomy to the third time of admission to hospital for chemotherapy. Data of demographic characteristics and depression were collected by using the General Questionnaire and Chinese version of Zung Self-rating Depression Scale (ZSDS) respectively. One pre-test (the day before radical mastectomy) and three post-tests (the day before discharge from hospital, the second and third admission to hospital for chemotherapy) were utilized. Duration of hospital stay was calculated from the first day after radical mastectomy to the day of discharged from hospital.

RESULTSThe mean depression score of all subjects was 37.19 ± 6.30. Thirty-six cases (30%) suffered from depression symptoms, with 26 (72.2%) mild depression cases, 9 (25.0%) moderate depression cases, and 1 (2.8%) severe depression case. After music therapy, depression scores of the experimental group were lower than that of the control group in the three post-tests, with significant differences (F = 39.13, P < 0.001; F = 82.09, P < 0.001). Duration of hospital stay after radical mastectomy of the experimental group ((13.62 ± 2.04) days) was shorter than that of the control group ((15.53 ± 2.75) days) with significant difference (t = -4.34, P < 0.001).

CONCLUSIONSMusic therapy has positive effects on improving depression of female patients with breast cancer, and duration of hospital stay after radical mastectomy can be reduced. It is worthy of applying music therapy as an alternative way of nursing intervention in clinical nursing process of caring female patients with breast cancer.
