Gender Differences in Correlations Between the Content of Elements in Rain Water and the Frequency of Hospitalization for Arterial Hypertension, Chronic Obstructive Pulmonary Disease, and Psoriasis in Opole Voivodship, Poland, During 2000–2002

The aim of this work is to show and give a plausible explanation to gender-dependent differences in correlations between the content of selected elements in rainwater and the frequency of hospitalization by reason of arterial hypertension, chronic obstructive pulmonary disease (COPD), and psoriasis in the area of Opolskie Voivodeship, Poland, during the period 2000-2002. The elements analyzed were sodium, potassium, calcium, magnesium, manganese, iron, total phosphorus, total nitrogen, ammonium nitrogen, zinc, copper, lead, cadmium, nickel, chromium, chloride, nitrate, and sulfate. Hospitalization due to arterial hypertension was more frequent in women, whereas those for COPD and psoriasis were more frequent in men. In the case of women hospitalized for arterial hypertension, the correlations were low, except for zinc (r = 0.47) and for cadmium (r = 0.43). In men hospitalized for COPD, all of the correlation coefficients were higher than 0.4, except for phosphorus. The coefficients for nickel, ammonia nitrogen, and total nitrogen ranged from 0.5 to 0.6 and the remaining elements from 0.6 to 0.7. In women, the correlation was limited to five elements where the coefficient was r > 0.4 for chloride, calcium, nitrate, phosphorus, and chromium. In cases of hospitalization for psoriasis, the correlation in men was between 0.4 and 0.5 for chloride, phosphorus, copper, lead, and total nitrogen and greater than 5 for sulfate, potassium, calcium, iron, manganese, nitrate, and ammonium nitrogen. The correlation in women was between 0.48 and 0.5 for ammonium nitrogen and phosphorus.

Gender differences in correlations among cardiovascular risk factors

Although the clustering of a few specific cardiovascular risk factors is known as the metabolic syndrome, sex-specific differences in correlations among risk factors have not been thoroughly examined. The analysis was undertaken to detect gender differences in correlations among cardio-vascular risk factors. Correlations among age, body mass index, systolic and diastolic blood pressures, and serum levels of fasting blood sugar (FBS), triglycerides (TG), high- and low-density lipoprotein cholesterol, high-sensitivity C-reactive protein (CRP), and uric acid were analyzed in apparently healthy Japanese men and women with TG<400 mg/dL and FBS<126 mg/dL. Among the 136 men and 136 women examined, the frequency of significant correlations was marginally higher in women than in men: 28/45 correlations versus 17/45 correlations, respectively (P=0.017). Of a total of 45 possible correlations, 5 were marginally or significantly stronger in women, whereas no correlations among these risk factors were marginally or significantly stronger in men (P=0.021). These gender differences were considerably attenuated after adjustment for age. However, a significant sex-specific difference was observed in the correlation between TG and rank transformation of CRP, even after adjustment for age (P<0.01). Correlations among cardiovascular risk factors were marginally stronger in women than in men. These results suggest that the existence of 1 additional risk factor may increase the risk of cardiovascular disease more steeply in women than in men.

Suicide Risk Among Persons with Foreign Background in Denmark

There is a dearth of knowledge about factors correlated with suicide risk among minority groups in Western societies. In the present study we compared suicide risk among persons with foreign background with that of the majority population to determine whether certain minority groups are at a particular risk for suicide, as well as to illuminate gender differences herein. Suicide risk was generally higher among persons with foreign background compared with the majority population and the risk was highest among Nordic-born persons. Overall, suicide risk was significantly lower among Asian-born persons; however, there were gender differences in correlations between ethnicity and suicide risk.

Gender differences in reactive and proactive aggression.

The purpose of our investigation was to study gender differences in proactive and reactive aggression in a sample of 323 clinically referred children and adolescents (68 females and 255 males). Proactive aggression and reactive aggression were assessed using the Proactive/Reactive Aggression Scale. Demographic, historical, family, diagnostic, and treatment variables were entered into stepwise regression analyses to determine correlates of proactive and reactive aggression in males and females. Results reveal high rates of aggression in both males and females in the sample. Self reported drug use, expressed hostility, and experiences of maladaptive parenting were correlated with proactive aggression for both genders. Hyperactive/impulsive behaviors were correlated with male reactive aggression. An early age of traumatic stress and a low verbal IQ were correlated with female proactive aggression. Gender differences in correlates of proactive and reactive aggression may provide possible targets for research, prevention, and treatment efforts focused on reducing maladaptive aggression in clinically referred youth.

Gender differences in correlates of depressive symptoms in adolescents

Purpose: To determine: (a) what demographic and psychosocial factors are associated with elevated levels of depressive symptoms in adolescence; (b) whether girls and boys show different profiles of correlates and probable risk factors for depressive symptoms; and (c) what the implications are of these results for future research directions and policy decisions. Methods: Using a nationally representative sample of adolescent school students in Grades 5–12, the Commonwealth Fund Adolescent Health Survey assessed depressive symptoms as well as a number of variables posited to be risk factors and correlates of depression. Results: Depressive symptoms were found to differ by gender, age, socioeconomic status, and ethnicity. In addition, life stress, social support, and coping were associated with depressive symptoms. Importantly, stress and social support appear to be particularly salient aspects of depression among girls. Both physical and sexual abuse were strongly linked with depression for both boys and girls, with sexual abuse having a stronger impact among boys. Finally, high levels of depressive symptoms were associated with increased use of both mental and physical health care resources among boys and girls. Conclusions: The correlates of depression in this adolescent sample closely resemble those seen in adult samples, including demographic and psychosocial variables. Some psychosocial variables, such as stress and social support, may have a greater impact on depressive symptoms for girls than for boys. Results of this study also have important implications for the health care system, given that higher levels of depressive symptoms were found to be associated with greater utilization of physical health care resources.

Correlations of plasma growth hormone with somatostatin, gonadal steroid hormones and thyroid hormones in rainbow trout during sexual recrudescence

The study explores the interrelationships among growth hormone (GH), somatostatin-14 (SRIF), non-esterified fatty acids (NEFA), gonadal steroid hormones and thyroid hormones (THs) in sexually recrudescent rainbow trout ( Oncorhynchus mykiss) to examine aspects of the complex set of physiological changes associated with gonadal growth and maturation. Females exhibited significant decreases in plasma SRIF, NEFA and triiodo- l-thyronine (T 3) concentrations, and a significant increase in plasma GH concentration associated with gonadal maturation, whereas in males, only SRIF and NEFA concentrations showed significant changes during testicular maturation. The declining SRIF levels during gonadal recrudescence may indicate a role for the hormone in the energy repartitioning processes that occur in both sexes at this time. Correlation analysis of plasma variables revealed a direct correlations between plasma NEFA and 17β-estradiol (E 2) in females, an inverse correlation between NEFA and testosterone (T) in males, inverse correlations between GH and SRIF in both males and females, and inverse correlations between THs and SRIF concentrations in females. These marked gender differences in correlations likely reflect the different physiological challenges faced by the two sexes and emphasizes the need to consider gender, as well as maturity when studying the interactions of hormones.

Gender differences in correlates of disablement among the elderly in Egypt

The purpose of this paper is to examine gender-specific models to determine whether different combinations of correlates are associated with male and female disablement, using a sample of non-institutionalized elderly persons in Egypt. Because women and men have different work, family, and household roles, as well as different health risks, it is reasonable to assume that there may be differing correlates for disablement for elderly males and females. The dichotomous dependent variable indicates problems, or the inability, in performing at least one of six activities of daily living (ADL). Of interest is the association of health, economic, and family variables, controlling for age. Logistic regression models are estimated for the total, male, and female samples. The results indicate that for males, having to stop working due to illness and having an unattended medical need are associated with higher odds for disablement as compared with females. Additionally, illiteracy increases the odds for male disablement, yet it has no effect on female disablement. Having experienced an injury in the past year is associated with disability for females, as is spending a lifetime in a rural setting and currently living in a fair to poor residence. Also for the females, increased number of living children significantly increases the odds for functional disability. Separate male and female models were estimated for each of the six ADL items. The trends indicated that the model covariates were more useful in modeling female disabilities in personal care activities, rather than problems with eating and mobility. The health variables were significantly associated with most of the specific ADL problems for the males.

Gender differences in correlations of cerebral glucose matabolic rates in young normal adults

Correlational analysis of normalized regional cerebral metabolic data obtained by positron emission tomography, in healthy subjects in the ‘resting’ state (eyes covered, ears plugged) using [ 18F]2-fluuro-2-deoxy- dgllucose, demonstrated gender differences in patterns of functional associations. Fifteen women and 18 men (< 40 yr) were scanned with a Scanditronix PC1024-7B tomograph. The brain was divided into 65 regions of interest (ROIs). There were no differences between men and women in global or regional metabolic rates, or in metabolic right-left asymmetries. Although the total number of significant correlations did not differ between men and women, patterns differed: female correlations r F were more positive than male correlations r M more often than r M > r F; and most r F > r M cases involved left frontal and sensorimotor ROIs, whereas most r M > r F cases involved right sensorimotor and occipital ROIs. The finding demonstrate gender differences in the pattern of functional neocortical interactions at the ‘resting’ state.

Gender differences in correlates of marital satisfaction

Abstract A sample of 51 couples was used to test the hypothesis that previously; reported gender differences in the utility of different predictors of marital satisfaction would not appear in dual-career couples where husbands and wives both have high commitment to their work relative to their family. From an initial sample of 89 couples, 25 dual-career couples and 26 traditional couples were selected on the basis of the relative commitments to work and family of each partner. A comparison of the correlates of marital satisfaction among husbands and wives in these two subsamples provided some support for the hypothesis. In traditional couples, discrepancy between preferred and actual roles, and appraisal of partner's performance of sex-typed roles were more highly related to females' than to males' marital satisfaction, while job satisfaction was a significant correlate of marital satisfaction among males but not among females. These gender differences were not observed in dual-career couples. Self-esteem...
