ABSTRACTOlder people who engage in sports and exercise in a group render greater benefits for socio-psychological aspects compared to exercising alone. The aim of this study was to identify the prevalence of specific types of sports and exercise groups and the association with self-rated health, depressive symptoms, and frequency of laughter among community-dwelling older people. We used cross-sectional data from the 2016 Japan Gerontological Evaluation Study and analysed 63,465 males and 68,497 females aged ≥65 years. The top three most popular types among males were golf (11.3%), walking (8.4%), and ground golf (6.3%). Among females, the top three were fitness exercises (13.8%), walking (8.3%), and weight exercises (6.2%). After adjusting for potential confounders, engaging in golf with a group was significantly related with excellent self-rated health (prevalence ratio, PR, 1.31 in male and 1.78 in female), low depressive symptoms (PR, 0.70 and 0.71), and a high frequency of laughter (PR, 1.12 and 1.13). Among females, walking displayed a significant relationship with all three characteristics (PR, 1.23, 0.79, and 1.06, respectively). Golf in older males and walking in older females might be the first choice for an effective programme to spread sports and exercise groups within the older Japanese community. 相似文献

Child welfare involvement has been linked to child behavioral health issues, including increased likelihood of internalizing mental health problems such as depression and anxiety, and externalizing behavioral problems such as oppositional behaviors and substance use problems. One predictor of child behavioral health is caregiver mental health. Although, there remains a specific gap associated with identification of factors among caregivers that are associated with longitudinal child behavioral health trajectories. Using LONGSCAN, we explore the effects of caregiver depression on the behavioral health of children over time. Multilevel mixed-effects linear regression models showed that children with a caregiver who reported depression showed significantly higher internalizing behavioral problems over time, and significantly larger decreases in externalizing behavioral problems over time, compared to children with a caregiver who reported no depression. These findings emphasize that early interventions geared towards jointly assessing and treating parent and child mental health issues in the child welfare system may be successful at improving future behavioral health outcomes. 相似文献

Background: Retirement from professional sport has been recognised as a major psychological stressor, and there is a need to identify factors that increase the risk of mental health problems after career termination. The current study examined associations between career-ending injury, chronic pain, athletic identity, and depressive symptomology in retired professional footballers. Methods: A cross-sectional study was performed with 307 retired male footballers who had played within a professional United Kingdom league. Participants completed measures of depressive symptoms (Short Depression-Happiness Scale), chronic pain (Pain Intensity Numerical Rating Scale), and athletic identity (Athletic Identity Measurement Scale), and reported their reasons for retirement. Results: A total of 48 participants (16%) met the cut-off score for possible cases of clinically relevant depression. These participants were more recently retired, and had higher athletic identity than those without depressive symptoms. Former players with depressive symptoms were more likely to cite injury as a retirement reason, and report higher levels of ongoing injury-related pain. Multivariate logistic regression revealed that the presence of depressive symptoms was independently associated with retirement through injury (OR?=?3.44; 95% CI?=?1.39, 8.51), higher pain levels (OR?=?1.38; 95% CI?=?1.02, 1.86), and increased athletic identity (OR?=?1.28; 95% CI?=?1.14, 1.44). Conclusions: Career-ending injury is strongly associated with higher odds of depressive symptomology during retirement, while experiencing chronic pain, and maintaining a high sense of athletic identity, are additional potential contributors. 相似文献

Externally Contingent and Unstable Self‐Worth as Predictors of Depression in College Women: A 3‐Month Study 下载免费PDF全文
Frederick G. Lopez Brittany Thorne Sydney Schoenecker Kevin Siffert Rebecca Chaliman Erica Castleberry 《Journal of College Counseling》2014,17(2):102-115
Undergraduate women completed measures of externally contingent self‐worth, self‐esteem instability, and depression at the beginning (Time 1) and again 3 months later near the end (Time 2) of an academic semester. Findings indicated that when Time 1 depression scores were controlled for, each Time 1 facet of self‐esteem made significant contributions to Time 2 depression scores. Implications of these findings for the counseling of depressed college students are discussed. 相似文献

考虑二阶常系数线性微分方程的降阶法.首先,写出二阶齐次常系数线性微分方程的特征方程,求出特征方程的两个特征根;然后,利用积分因子乘以微分方程和导数的运算,将二阶常系数线性微分方程化为一阶微分形式;最后,将一阶微分形式两边同时积分,求解一阶线性微分方程,可求得二阶常系数线性微分方程的一个特解或通解.利用降阶法,可以求得微分方程的一个特解或通解.其计算方法简单和方便,在实际中具有应用价值。 相似文献

临床心理学指出,心理健康状况通过人的行为表现,其中包括网络行为.传统的心理健康测评以自陈量表的形式为主.这不但要耗费大量的人工处理工作,更不能做到实时进行心理健康状态的获取.针对传统方法的不足,本文旨在通过新浪微博的环境,预测用户的心理健康状况,特别是抑郁和焦虑问题.通过批量获取微博用户的网上数据,验证了传统理论中人格和心理健康之间的相关性,并采用多任务回归学习预测微博用户的心理健康状况.结果表明,心理健康问题可以通过网络行为反映出来,通过用户的微博使用情况,预测其抑郁和焦虑的程度是可行的. 相似文献
