Consequences of non-marital fertility are mostly negative particularly in developing countries. In Namibia, although premarital childbearing has been reported to be high and increasing, no studies have explicitly analyzed factors influencing non-marital fertility. This paper uses data from the 2006/7 Namibia DHS to establish the determinants of non-marital fertility among women by applying a two-part model, with one part to describe the presence of non-marital birth and the other part to explain its intensity （number of children born）. Using the number of children ever born as an outcome, we explored various count data models. Based on the Voung statistics model comparison, we settled for the Hurdle logit Negative Binomial regression to model the number of non-marital births. Non-marital fertility in Namibia is associated with the age, with young women likely to have lower fertility compared to older women. Women with secondary or higher education had lower fertility compared those with no formal education. Findings also show that rural women higher fertility propensity compared to their urban counterparts even though there was no significant difference in fertility intensity. With regard to socio-economic status, fertility intensity decreased as the women got richer. Intervention efforts should focus on promoting education among girls and women especially in rural areas to improve their socio-economic status, reduce teenage pregnancy and non-marital fertility.展开更多

With the rapid development of the rural economy, along with urbanization and industrialization, it has been further increased the degree of market-oriented agriculture. The contradiction between big market and small-scale production is more prominent; such small -scale decentralized form of management has begun not to meet agricultural development request and the market economy development. It needs changes to moderate scale. Eleventh Five-Year Plan and construction of new socialist village require clearly various forms of appropriate scale.展开更多

It is imperative to assess poverty dynamics in a timely and effective manner in China's rural areas. Therefore, we used the poverty gap index to investigate the poverty dynamics in China's rural areas during 2000–2014 at the national, contiguous poor areas with particular difficulties and county scales. We found that China made significant achievements in poverty alleviation during 2000–2014. At the national scale, the number of impoverished counties decreased by 1428, a reduction of 97.28%. The rural population in impoverished counties decreased by 493.94 million people or 98.76%. Poverty alleviation was closely associated with economic development, especially with industrial development. Among all 15 socioeconomic indicators, the industrial added value had the highest correlation coefficient with the poverty gap index(r = –0.458, p<0.01). Meanwhile, the inequality of income distribution in the out-of-poverty counties has been aggravated. The urban-rural income gap among the out-of-poverty counties increased by 1.67-fold, and the coefficient of variation in rural per-capita income among the out-of-poverty counties also increased by 9.09%. Thus, we argued that special attention should be paid to reducing income inequality for sustainable development in China's rural areas.展开更多

Methods： All suspected cases of supracondylar humeral fracture reporting to emergency or outpatients department were analysed for various epidemiologic parameters including age, sex, laterality, time of presentation, associated injuries, neurovascular complications and classification over a period of four years. Results： We analysed a total of 263 patients and most of the fractures were seen in 5-8-year age group with a mean of 7.9 years. A total of 157 cases were males and non-dominant extremity was involved in 65% of fractures in our series. Fall on outstretched hand was the predominant cause of injury and fall from rooftop was the predominant mode. In all patients, 36.12% reported to our hospital 1 week after injury, 39.92% presented to hospital within 48 h after trauma and the remaining 23.95% presented 48 h to 1 week after trauma. None had a bilateral injury. Gartland type 3 fractures constituted 54.37% of patients, followed by type 1 （23.95%） and type 2 （21.67%）. Conclusion： Almost one fourth of supracondylar humeral fractures in children can be prevented by installing railing of rooftops and stairs. It is necessary to educate people on hazards of treatment by traditional bonesetters. Moreover, the children with supracondylar humeral fractures should be screened for associated injuries.展开更多
