油田作业人员职业紧张状况调查及心理障碍的影响因素分析

目的:调查油田作业人员职业紧张状况,并分析心理障碍的影响因素。方法:通过分层整群抽样法纳入600例油田作业人员作为研究对象,采用职业紧张量表(OSI-R)以及症状自评量表(SCL-90)对油田作业人员的职业紧张程度以及心理障碍状况进行评估,并按照SCL-90评分将其分为研究组(SCL-90评分160分)214例与对照组(SCL-90评分≤160分)386例,采用多因素Logistic回归分析油田作业人员心理障碍的影响因素。结果:研究组年龄45岁、受教育程度为本科及以上、工龄20年人数占比均高于对照组(均P0.05)。研究组职业任务问卷(ORQ)、个体紧张反应(PSQ)评分均高于对照组(均P0.05)。研究组重度职业紧张程度人数占比高于对照组(P0.05)。经多因素Logistic回归分析发现:年龄45岁、受教育程度本科及以上、工龄20年、重度职业紧张均是油田作业人员心理障碍的独立危险因素(均P0.05)。结论:油田作业人员职业紧张状况不容乐观,重度职业紧张、年龄较小、工龄较短及受教育程度较高的油田工作人员发生心理障碍的风险往往较大。临床工作中可通过降低油田作业人员的职业紧张程度,继而达到降低心理障碍发生几率的目的。     

Effects of different environmental enrichment devices on cage stereotypies and autoaggression in captive cynomolgus monkeys

Autoaggression and stereotypies in individually housed cynomolgus monkeys were compared in a standard primate cage and an enriched playpen environment. Stereotypy and autoaggression were markedly reduced in the playpen, but reappeared on return to the home cage. Some of the various activities available in the playpen but not others engaged the animals' attention.     

Economic development,intergenerational mobility,and health in South Korea

A growing number of studies reported the association between social mobility and health. However, few studies investigated whether the association varies by age group. Drawing on the economic environment that facilitated social mobility in South Korea, we postulate each age group had a different extent of social mobility, which would vary with the extent of economic growth and affect the association between social mobility and health. We used data from KDI National Happiness Survey 2018 and measured perceived mobility using respondents’ perceived social position and their parents’ social position. We examined whether social mobility was associated with self-rated health and psychological well-being. The upwardly mobile individuals were more likely than the stable ones to report ‘happy’. Such a positive association between upward mobility and happiness was consistently found when the sample was restricted to the ages 30–59 and 40–49. For self-rated health, the downwardly mobile individuals were less likely to report good health. However, no significant difference in self-rated health was found after the youngest and oldest age groups were excluded. We found that perceived social mobility was strongly associated with psychological well-being rather than self-rated health. Moreover, we found a stronger association between upward mobility and happiness among the aged 40–49, who had the largest proportion of upwardly mobile individuals and spent their adolescence during rapid economic growth. The findings underscore the importance of the economic and social context in which individuals perceive their social position and shape their well-being.     

Relationship between thermophysiological responses and psychological thermal perception during exercise wearing aerobic wear

This paper studies the relationships among human physiological and psychological thermal and moisture responses in tight-fit aerobic wear. Results showed that both physiological and psychological responses were significantly influenced by time, garment, body location and some of their interactions. Objectively measured skin humidity and moisture sensation at individual locations were highly correlated and significant at p levels of 0.01. Overall clothing comfort may be best described with thermal sensation at outer thigh, humidity at inner thigh. The correlation coefficient of predicted with experimental clothing comfort score was 0.76, and a t-test showed that there was no significant difference between the two data sets.     

Behavioral Weight Control for Overweight Adolescents Initiated in Primary Care

Objective: This study evaluates the post-treatment and short-term follow-up efficacy of, as well as participant satisfaction for, a 4-month behavioral weight control program for overweight adolescents initiated in a primary care setting and extended through telephone and mail contact. Research Methods and Procedures: 44 overweight adolescents were randomly assigned to either a multiple component behavioral weight control intervention (Healthy Habits [HH]; n = 23) or a single session of physician weight counseling (typical care [TC]; n = 21). Weight, height, dietary intake, physical activity, sedentary behavior, and problematic weight-related and eating behaviors and beliefs were assessed before treatment, after the 4-month treatment, and at 3-month follow-up. Participant satisfaction and behavioral skills use were measured. Results: HH adolescents evidenced better change in body mass index z scores to post-treatment than TC adolescents. Body mass index z scores changed similarly in the conditions from post-treatment through follow-up. Behavioral skills use was higher among HH than TC adolescents, and higher behavioral skills use was related to better weight outcome. Energy intake, percentage of calories from fat, physical activity, sedentary behavior, and problematic weight-related or eating behaviors/beliefs did not differ by condition or significantly change over time independent of condition. The behavioral intervention evidenced good feasibility and participant satisfaction. Discussion: A telephone- and mail-based behavioral intervention initiated in primary care resulted in better weight control efficacy relative to care typically provided to overweight adolescents. Innovative and efficacious weight control intervention delivery approaches could decrease provider and participant burden and improve dissemination to the increasing population of overweight youth.
