This study aimed to investigate the growth and nutritional status of children under five years of age from urban low-income families in China. There were 169 children aged 25–60 months recruited from Xiangtan and Jilin, two cities with a population of 2.81 million and 4.26 million respectively, in China in this cluster cross-sectional study. Data were collected on demographic and socioeconomic characteristics, the feeding practices and the incidence of anemia and diarrhea. The results showed that the prevalence of low birth weight and macrosomia was 7.1% and 9.5% for the two cities, respectively, which was higher than that for other cities in China(1.5% and 5.9%). Of all the sampled children, 14.6% and 8.2% suffered anemia and diarrhea, respectively. Multivariate analysis showed that legumes or nuts fed in a 24-h recall increased the risk of anemia(OR=4.9). Children whose caregivers began to introduce complementary foods relatively late would have high diarrhea prevalence(OR=1.4). In conclusion, the prevalence of anemia and diarrhea in under-five children from urban low-income families in China is relatively high. The growth and nutritional status of these children is greatly affected by feeding practices. A series of measures should be taken by relevant government departments to improve the health of these children.展开更多

Methods Data sets of boys and girls at the age of 7-18 years collected from the series of Chinese national surveillance on students' constitution and health (CNSSCH) between 1985 and 2000 were divided into five socioeconomic and demographic groups, while BMI classification reference proposed by Working Group on Obesity in China (WGOC) was used as screening reference to calculate the prevalence and trends of overweight/obesity in these groups. Results In 2000, the prevalence of obesity and overweight in boys aged 7-18 years was 11.3% and 6.5% in Beijing, 13.2% and 4.9% in Shanghai, 9.9% and 4.5% in coastal big cities, and 5.8% and 2.0% in coastal medium/small-sized cities, respectively, while the prevalence of of obesity and overweight in girls of the same age group was 8.2% and 3.7% in Beijing, 7.3% and 2.6% in Shanghai, 5.9% and 2.8% in coastal big cities, and 4.8% and 1.7% in coastal medium/small-sized cities, respectively. The prevalence of obesity was low in most of the inland cities at an early stage of epidemic overweight. The epidemic manifested a gradient distribution in groups, which was closely related to status (SES) of the study population. However, a dramatic and steady increasing trend was witnessed among all sex-age subgroups in the five urban groups, and such a trend was stronger in boys than in girls, and much stronger in children than in adolescents. Conclusion Although China is at an early stage of epidemic obesity by and large, the prevalence of obesity in her urban population, particularly in coastal big cities has reached the average level of developed countries. The increasing trend has been rapid since early 1990s, and the increments in obesity and overweight are exceptionally high. The prospect of epidemic obesity in China is in no way optimistic. Therefore, preventive program should be focused on the improvement of the balance between caloric intake and energy expenditure, and interventions aimed at changing children's life styles.展开更多

Thus, the study aimed to determine the etiology of diarrhea among severely malnourished (z score ?3.00 SD) children in rural and urban Bangladesh. From the database (2000-2011) of Diarrheal Disease Surveillance Systems (DDSS) at rural Matlab and urban Dhaka hospitals of icddr,b, 2234 and 3109 under-5 children were found severely malnourished (underweight, stunted or wasted) respectively. Two comparison groups [moderately malnourished (MM) and well-nourished (WN)] were randomly selected in a ratio of 1:1:1. Children with all categories of SM were more likely to be infected with Vibrio cholerae (rural—11%;urban—15%), Shigella (16%;9%), Salmonella (1%;2%) and Campylobacter (3%;4%);and less likely to have rotavirus (25%;20%) compared to only one SM category. Isolation rate of Vibrio cholerae was significantly higher among SM both in rural and urban children (7%;13%) than those of MM (5%;10%) and WN (2%;8%) and lower for rotavirus (30%;31%), (34%;43%), (35%;47%) respectively (p 0.01). However, for Shigella it was only higher among rural SM children (11%) [MM (9%), and WN (8%) (p 0.01)]. The isolation rate of Salmonella in SM (2%) was similar to that in MM (2%;p = 0.72) but significantly higher than that in WN (1%;p 0.01) among urban children. Isolation rates of bacterial enteric pathogens were higher but rotavirus was lower in SM children in both rural and urban area with geographical heterogeneity.展开更多

In Ethiopia, several interventions are going on to reduce morbidity, and mortality of children. The objective of the study was to assess the prevalence and associated factors of diarrhoeal diseases among under-five children in the City Administration of Bahir Dar. Methods: A community based cross-sectional study was conducted on a sample size of 667 mothers/caregivers having under-five children. Participants were selected through multistage sampling technique. Structured questionnaire and observation checklist were used to collect data. It was analyzed using SPSS version 16 for windows. Logistic regression was applied to measure possible associations. Strength of association, and statistical significance was measured using odds ratio and confidence interval at 95% confidence level. Results: A total of 667 mothers/ caregivers with under-five children were included in the study. Two-week prevalence of diarrhoea was 21.6%. Households in rural part of the city (OR: 2.82, 95%CI: 1.66 - 4.81), monthly income ≤ birr 500 (OR: 2.27, 95%CI: 1.44 - 3.57, failure to use separate container for storing drinking water (OR: 1.78, 95%CI: 1.17 - 2.70), presence of human excreta in the compound (OR: 1.88, 95% (1.15 - 3.06) were found to be predictors of childhood diarrhoea. Conclusion: Diarrhoeal diseases remain serious public health challenge in rural as well as urban set ups in Ethiopia with particular reference to Bahir Dar City, despite several interventions over decades. Therefore, interventions, and strategies applied so far to eliminate diseases of poverty including diarrhoeal diseases should be re-visited.展开更多

Then proposed hypotheses and the reliability of the observation variables were respectively examined with ANOVA and factor analysis. The statistical analysis software SPSS19.0 was used to analyze the data.Findings: Our results showed that 1) differences did exist in school and social reading environment between urban and rural children in Chongqing Reservoir Area; 2) differences in family reading environment between urban and rural children in Chongqing Reservoir Area were not obviously observed.Research limitations: The empirical data were collected from only one county of Chongqing Reservoir Area, which may have partially affected the generalization of our conclusions. In addition, the response rate of questionnaires was comparatively low due to a relatively limited research period. Practical implications: This study would provide some reference for governments, libraries, schools and families to consider how to jointly narrow the gap in the extracurricular reading circumstance between urban and rural children in Chongqing Reservoir Area.Originality value: This is one of the first studies to explore similarities and differences in extracurricular reading environment between urban and rural children in Chinese povertystricken areas, which will help research communities to gain a deeper understanding of children’s reading environment in Chinese Reservoir Area.展开更多

The aim of the study was to explore the proportion of childhood obesity in the primary school children of middle and upper-middle income group in capital city and to gather information on their dietary pattern and physical activity. Methods: One hundred and fifty children (age 9 ± 1 years, height (ht) 118 ± 20 cm, weight (wt) 36 ± 8 kg, wt/ht% 126 ± 24, mean ± SD) were selected purposively from the primary schools of Dhaka city. On the basis of predefined scoring, subjects were classified as underweight, normal, overweight and obese if their weight-for-height values were 120% of median values for Bangladeshi children respectively. Dietary intake and energy expenditure of the study subjects were calculated by standard techniques. Results: The proportion of childhood overweight and obesity was 52% and 20%. The proportion of overweight and obesity was higher (78%) among girls compared to boys (54%). Similarly, height, weight and other anthropometrics indices were significantly (p < 0.05) higher in girls compared to boys. The daily intake of carbohydrate and protein was significantly (p < 0.05) higher among obese group. Total energy balance was significantly correlated with weight-for-height% (r = 0.541, p = 0.0001). Conclusions: A higher proportion of overweight and obesity had been found in girls’ children than their counter parts in this study. Positive energy balance with higher energy intake from carbohydrate and fast/processed food culture habit were found among primary school children of middle and upper-middle income group in the capital city of Bangladesh.展开更多
