2018年4—5月在四川省南充市城区采用便利抽样,以已婚且未育或已育一个小孩的育龄妇女为研究对象,采用自制匿名问卷,以面对面的形式收集资料,了解实施全面二孩政策后南充市育龄妇女的生育意愿,为南充市的人口研究提供参考依据。在213名调查对象中,56人(26.3%)有二孩生育意愿,140人(65.7%)无二孩生育意愿,17人(8.0%)不确定是否生育二孩。南充市被调查者的理想子女个数均值为1.46,意愿子女个数均值为1.27。不同文化程度(χ2=7.512)、配偶月收入(χ2=12.641)、理想子女数(χ2=66.401)、一孩性别(χ2=5.441)的育龄妇女间二孩生育意愿差异有统计学意义(P<0.05)。Logistic回归分析显示,第一个孩子性别为女孩(OR=2.641,P=0.021)、丈夫月收入越高(OR=1.761,P=0.028)、理想子女数多于1个(OR=29.040,P<0.001)的育龄妇女更有意愿生育二孩。南充市城区二孩生育意愿处于较低水平,经济收入、理想子女数、一孩性别会影响育龄妇女的二孩生育意愿。全面二孩政策对于促进育龄妇女生育二孩的效应有限,应当建立相关的配套政策,以促进全面二孩政策的实施。 相似文献

This study contributes to earlier research on homeownership and childbearing by taking into account the potential simultaneity between these two life events. A dataset comprising three different Swedish birth cohorts suggests that these are events that are indeed simultaneous. Different tests indicate that taking this simultaneity into account gives an overall statistically significant improvement of the model fit. However, this result is most obvious for those young adults who faced increasing problems on the housing market. The childbearing decision of these cohorts also seems to be more sensitive to changes in the user cost. 相似文献

Among policymakers, a common perception surrounding the effects of cash transfer programmes, particularly unconditional programmes targeted to families with children, is that they induce increased fertility. We evaluate the Zambian Child Grant Programme, a government unconditional cash transfer targeted to families with a child under the age of 5 and examine impacts on fertility and household composition. The evaluation was a cluster randomized control trial, with data collected over 4 years from 2010 to 2014. Our results indicate that there are no programme impacts on overall fertility. Our results contribute to a small evidence base demonstrating that there are no unintended incentives related to fertility due to cash transfers. 相似文献

Near misses are a special kind of reinforcement which increases one’s desire to play. The aim of this paper is to examine
the perception of near misses in normal population. We used a slot machine simulation running on a PC, where participants
had to play four rounds with different near miss ratios (0, 15, 30 and 45%). Our sample consisted of 159 individuals with
mean age of 22.8 and with no or little gambling experience. For data analysis we used chi-squared goodness-of-fit test and
exact binomial test. Despite the fact, that there was a notable effect of near misses results showed that the subjects could
not perceive trials of them. 相似文献

The objective of this work was to summarise and evaluate the evidence showing that physical activity is a protector factor as regards falls in older people. Relevant studies were identified through a systematic search in the MEDLINE and Cochrane Library, under the keywords of accidental fall/numerical data and risk factors, and with the bibliographies of retrieved papers. The combined odds ratio (OR) [95% confidence interval] for physical activity was 0.75 [0.64, 0.88] with moderate heterogeneity (I 2?=?33%). For fall injury, it was 0.59 [0.47, 0.74] and, for falls in general, it rose to 0.94 [0.76, 1.17] with nil heterogeneity. The combined OR for sedentary factors was 1.14 [1.10, 1.82] with moderate heterogeneity (I 2?=?36%). Regular physical activity in daily life yields significant reduction in falls in older people, especially falls with injuries. 相似文献

China??s oldest old population is estimated to quadruple by 2050. Yet, poverty rate for the oldest old has been the highest among all age groups in China. This paper investigates the relationship between economic stress, quality of life, and mortality among the oldest-old in China. Both objective economic hardships and perceived economic strain are examined. We base our investigation on data drawn from the Chinese Longitudinal Healthy Longevity Survey conducted between 2000 and 2005. Our sample includes 10,972 men and women between the ages of 80 and 105 in 2000. The data show that about 16% of these oldest-old lived under economic stress in 2000. The risk factors that make one vulnerable to economic stress include age, being male, being widowed or never married, being a minority member, having no education, having no living children, and not having children as main source of income, and having no pension. Economic stress is negatively associated with indicators of quality of life, such as the quality of medical care and mental well-being. The poor quality of life contributes to the higher mortality rate for the oldest old who are under economic stress. Results also show that perceived economic strain increases the risk of mortality by 42% in rural areas, even after controlling for basic demographic characteristics, life style factors, and major health events.?For the rural oldest-old, having children as a main source of income and having access to pension alleviates the negative impact of economic hardship on mortality hazard by 23 and 66% respectively. However, in urban areas, economic stress has no direct impact on the hazard of mortality. 相似文献
