While most body image research has focused on young female populations, evidence has shown that as few as 12% of older women are satisfied with their body size. Recent studies have also highlighted how anti-aging discourses are promoting unrealistic body norms, which have shown to contribute to poor body image and altered health behaviors. A systematic review of empirical studies focused on older women’s perspectives of health, body image, and the aging body is presented. Findings support that body image is a persistent, lifelong issue for women and should be considered when implementing healthy aging policies and practices. 相似文献

Following every U.S. decennial census since 1960, the U.S. Census Bureau has evaluated the completeness of coverage using two different methods. Demographic analysis (DA) compares the census counts to a set of independent population estimates to infer coverage differences by age, sex, and race. The survey-based approach (also called dual system estimation or DSE) provides coverage estimates based on matching data from a post-enumeration survey to census records. This paper reviews the fundamentals of the two methodological approaches and then initially examines the results of these two methods for the 2010 decennial census in terms of consistency and inconsistency for age groups. The authors find that the two methods produce relatively consistent results for all age groups, except for young children. Consequently, the paper focuses on the results for children. Results of the 1990, 2000, and 2010 decennial censuses are shown for the overall population in this age group and by demographic detail (age, race, and Hispanic origin). Among children, the DA and DSE results are most inconsistent for the population aged 0–4 and most consistent for ages 10–17. Results also show that DA and DSE are more consistent for Black than non-Black populations. The authors discuss possible explanations for the differences in the two methods for young children and conclude that the DSE approach may underestimate the net undercount of young children due to correlation bias. 相似文献

Control‐based imputation for sensitivity analyses in informative censoring for recurrent event data 下载免费PDF全文

In clinical trials, missing data commonly arise through nonadherence to the randomized treatment or to study procedure. For trials in which recurrent event endpoints are of interests, conventional analyses using the proportional intensity model or the count model assume that the data are missing at random, which cannot be tested using the observed data alone. Thus, sensitivity analyses are recommended. We implement the control‐based multiple imputation as sensitivity analyses for the recurrent event data. We model the recurrent event using a piecewise exponential proportional intensity model with frailty and sample the parameters from the posterior distribution. We impute the number of events after dropped out and correct the variance estimation using a bootstrap procedure. We apply the method to an application of sitagliptin study. 相似文献

Objective: To help clarify the effect of gender on the bidirectional relationship between alcohol use and strenuous physical activity in college students. Participants: Five hundred twenty-four (52% female) college students recruited in August 2008 and 2009 and followed up in April 2009 and April 2011, respectively. Methods: Participants reported their alcohol use and strenuous physical activity on 2 occasions (baseline and follow-up) spaced approximately 1 or 2 years apart. Results: For females, alcohol use quantity at baseline was associated with increased strenuous physical activity at 1- and 2-year follow-ups, and alcohol use frequency at baseline was associated with decreased strenuous physical activity at 2-year follow-up. For males, alcohol use frequency at baseline predicted decreased strenuous physical activity at 1-year follow-up. Conclusions: Gender differences may be explained from an eating disorders perspective such that women use physical activity as a compensatory strategy to combat potential weight gain from calories consumed during alcohol use. 相似文献

Objective: To investigate sexual orientation differences in college men's motivations for HIV testing. Participants: 665 male college students in the Southeastern United States from 2006 to 2014. Methods: Students completed a survey on HIV risk factors and testing motivations. Logistic regressions were conducted to determine the differences between heterosexual men (HM) and sexual minority men (SMM). Results: SMM were more motivated to get tested by concern over past condomless sex, while HM were more often cited supporting the testing program “on principle” and wanting a free t-shirt. SMM and HM differed in behaviors that impact HIV risk and other demographics. However, differences in testing motivation by concern over past condomless sex or wanting a free t-shirt persisted when controlling for these demographic and behavioral differences. Conclusions: Appropriately designed HIV prevention interventions on college campuses should target SMM's distinct concern over past condomless sex as a testing motivation. 相似文献

Background
While the provision of maternity education across the perinatal period can increase the confidence and self-efficacy in childbearing women, there is still thought to be a lack of effective educational resources for parenthood. This study, conducted in Victoria, Australia, investigated women’s experiences of, and attitudes to education communicated in maternity service provision.Methods
189 women were recruited from a variety of settings to participate in a mixed-methods survey about their experiences of perinatal health service education.Findings
Of the sample of childbearing women, 153 (81%) reported attending antenatal classes. Women perceived their antenatal education as beneficial, though many women still felt unprepared beyond labour and birth. With respect to the hospital postnatal stay, findings suggested a variation among the content imparted to women across different Victorian maternity services, (e.g. rural women tended to be more dissatisfied with information received in relation to maternal emotional and physical health). Overall, women wished they had been more informed about breastfeeding and settling techniques, while a lack of information relating to social support initiatives for the postnatal period was also indicated. Women reported that they were missing educational and practical reinforcement of mothercraft skills.Conclusions
There is a need for a reorientation of perinatal health service education. A health promotion approach is suggested as it extends beyond the physical recovery from birth to encompass psychosocial factors; including perinatal morbidities that can disrupt the quality and experience of the transition to parenthood. 相似文献29.

This article provides my reflections and comments on the meta-analysis of situational crisis communication theory (SCCT) presented in this issue. The meta-analysis helps to crystallize strengths and weaknesses of SCCT and the research generated by the theory. No theory is perfect and every theory has limitations/boundaries. The meta-analysis helps to identify the boundaries for SCCT helping to understand when the theory works and when there are better options for informing crisis communication. By reflecting on the extant research, we can plot the direction for future research utilizing SCCT. 相似文献
