Job Strain, Workplace Discrimination, and Hypertension Among Older Workers: The Health and Retirement Study

Job strain has been associated with hypertension among younger workers; however, whether this relationship persists among older workers, particularly older racial/ethnic minorities, is unresolved. This study evaluated whether job strain and workplace discrimination are associated with hypertension and poor blood pressure control among older workers and whether these relationships vary by gender and race/ethnicity. Data were drawn from the Health and Retirement Study, and analysis was restricted to employed participants with complete information on job strain and blood pressure (N = 3,794). In adjusted models, high job strain was associated with lower likelihood of hypertension (odds ratio (OR): 0.75, 95% confidence interval (CI): 0.63, 0.89) relative to low job strain. Stratified analyses indicated this association was only significant among white (OR: 0.71, 95% CI: 0.58, 0.86) and male (OR: 0.61, 95% CI: 0.47, 0.79) workers. High job strain was not significantly associated with hypertension among African American (OR: 1.14, 95% CI: 0.63, 2.07) or Hispanic (OR: 0.56, 95% CI: 0.29, 1.09) workers. Workplace discrimination was not associated with hypertension among any group. Neither job strain nor discrimination was associated with poor blood pressure control. These findings suggest that persistence in work characterized by high job strain in later life may signal resilience to the influence of work-related stressors on health. Future research efforts should examine the factors that contribute to gender and racial differences in these relationships.     

莱麦草染色体组分析及染色体变异的观察

通过对有丝分裂中期及减数分裂终变期染色体数目统计,形态、行为的观察,发现莱麦草染色体呈现广泛的变异：有丝分裂中期株内染色体数目在2n＝11──56内变化,含有本物种染色体数目2n＝28的细胞仅占统计数的27．8％。减数分裂终变期出现36％具非整倍性的花粉母细胞,染色体数除数目变异外还有结构变异如Robertson易位等。本文对该种进行了染色体组分析,确认其为同源四倍体。同时对该物种株内产生混倍性的原因,在物种进化上的意义进行了探讨。

Adolescent-Rated Health and Intention to Attend College: Variation by Race/Ethnicity and Levels of Health Status

Quantify the relationships between adolescent self-reported health and college intention in a diverse sample including Asians. Data were used from 3,737 adolescents ages 12–17 who completed the 2003 California Health Interview Survey. Self-reported intention to attend college/university was compared to other plans. Multivariate logistic models predicting college intention by health status (poor/fair, good, or very good/excellent) were performed with the entire sample and for each race/ethnicity separately. Age, poverty, gender, rural residence, and parental college education were controlled. Participants were 44 % white, 36 % Hispanic, 11 % Asian, and 9 % black. Overall, 10 % reported poor/fair health, 30 % good health, and 60 % very good/excellent health. Whites were the most likely to report very good/excellent health and Hispanics least likely (χ²(6) = 11.85; p < 0.01). Eighty-one percent had college plans, which also varied by race/ethnicity with Asians most likely to report college intentions and Hispanics least likely (χ²(3) = 3.97; p < 0.05). In the overall multivariate model, adolescents in poor/fair health (OR: 0.53; 95 % CI: 0.34–0.83) and good health (OR: 0.59; 95 % CI: 0.45–0.78) were significantly less likely to plan on college compared to those in very good/excellent health. Variation was seen by racial/ethnic group. For whites and blacks, only good health significantly predicted less college intention (compared to very good/excellent health) while only poor/fair health significantly predicted less college intention for Hispanics and Asians. Very good/excellent health in adolescence was associated with greater college intention compared to both fair/poor health and good health, but this relationship varied by race/ethnicity.
