Physical symptoms and the interplay of work and family roles.

The paradigm underlying research on the relationship between work and physical-health symptoms in men has focused on workplace stressors and has ignored men's family roles. Research on women, work, and health suggests several necessary additions to this paradigm, including (a) a focus on job rewards and job concerns and (b) attention to the impact of family roles on the relationship between job rewards and concerns and physical health. We included these variables in a study of a disproportionate random sample of 403 employed 25- to 55-year-old women. Major findings are that (a) work rewards (e.g., helping others at work) are related to reports of low levels of physical symptoms; (b) work concerns (e.g., overload) are associated with reports of high levels of physical symptoms; (c) particular work rewards, which may be different for women than for men, mitigate the negative health effects of work concerns; (d) among employed mothers, satisfaction with salary is negatively related to physical-health symptoms; and (e) women in positive marriages or partnerships were more likely to reap physical-health benefits from the rewards of helping others at work and from supervisor support.

Race, class and multiple role strains and gains among women employed in the service sector.

Race and social class differences in the quality of job and parenting experiences, and multiple role gains and strains, are examined in a sample of 229 black and white female social workers and licensed practical nurses. Both race and class differences in job-role quality were found, but only class differences were found in parenting concerns. Race and class differences were found in multiple role gains and strains.

Consequences of fathers' participation in family work: parents' role strain and well-being.

The relation of fathers' participation in family work (child care and home chores) to parents' role strain and well-being was examined in an interview study of 160 Caucasian middle-class fathers and mothers of kindergarten and fourth-grade children. In half of the families, mothers were employed. Four forms of paternal participation were examined. Role-strain items referred to immediate and specific problems such as time and energy constraints and role conflicts. Well-being measures assessed self-esteem, life satisfaction, and quality of experience in the parental and marital roles. Regression analyses, carried out separately for fathers and for mothers, indicated that, contrary to expectation, when the level of fathers' participation was controlled maternal employment did not condition the relation between participation and the outcome variables. Findings varied for the different forms of participation. For fathers, higher levels of participation were associated with feeling more involved and competent as a parent and with being more critical of wives' patterns and parenting. For mothers, those whose husbands were more participant praised their husbands' parenting, but they were lower in life satisfaction and were more self-critical about their balance of work and family responsibilities.

Fathers' participation in family work and children's sex-role attitudes.

The relation between fathers' participation in family work (child care and home chores) and children's sex-role attitudes was examined in an interview study of 160 Caucasian middle-class families. Children were stratified by age level (5-year-olds and 10-year-olds), sex, and maternal employment status. 5 types of paternal participation were assessed--for example, total interaction time, performance of traditionally feminine home chores--using joint estimates by fathers and mothers. Children's attitudes were measured by questionnaire; their occupational aspirations were also assessed. Data are provided on the extent of fathers' participation for each of the 5 types assessed. The direct effects of paternal participation per se on children's attitudes were weak. Among fourth graders, mother's attitude toward the male role was the strongest predictor of stereotyping; children with nontraditional mothers were significantly less stereotyped.

Women's involvement in multiple roles and psychological distress.

Women's involvement in multiple roles was examined in relation to three stress indices: role overload, role conflict, and anxiety. Using hierarchical multiple regression analyses, effects of number of roles occupied; occupancy of the particular roles of paid worker, wife, and mother; and the quality of a woman's experience in her roles were analyzed. Data were from a disproportionate stratified random sample (N = 238) of Caucasian women between 35 and 55 years of age. For the total sample and for employed women, occupancy of the role of mother was related to two stress indices; occupancy of the role of paid worker was related to none. The quality of experience in the work and parental roles was a significant predictor of role overload; quality of parental role experience was a significant predictor of role conflict and of anxiety.

Patient noncompliance with postvasectomy semen examination protocol.

This study determined the degree of patient compliance with postvasectomy semen examination protocol for verbal instructions as compared with verbal augmented by written instructions. The addition of written instructions did not improve patient compliance, and for a significant majority of patients (68 to 76 percent) there was no laboratory verification of the effectiveness of the vasectomy procedure. Results of the study raise serious concerns about physician reliance on patient compliance for postvasectomy semen examination protocol as assurance of successful vasectomy. When the potential for fertility among vasectomized men is uncertain, the complication of an unwanted pregnancy will fall on the woman. Educating physicians in the problems and strategies for gaining patient compliance is as essential as education in competent surgical technique.

[Contamination of cotton seeds and of cotton seed cake by aflatoxin].

Following the discovery of aflatoxin M in cow's milk in the previous study, the contamination with aflatoxin of cotton-seed and cotton-seed cake which constitute the principal feed of local animals was measured. The samples were taken from 2 factories. The grain from the 1st factory was grown in the centre of the country in dry climate, and those from the 2nd source originated from the humid region of the north of Iran. The grain and cotton-seed cake from the 1st factory did not contain aflatoxin before storage. During storage the sample contamination amount and percent increased with time in both regions, with the dry less than the humid. In conclusion, Iranian cotton-seed and cotton-seed cake appear to be contaminated with aflatoxin B in 2 processes. The 1st is aflatoxin contamination before harvest, in the humid region of Iran; the 2nd is general storage aflatoxin contamination in both regions in which humidity and length of storage appear to be the principal factors.

Antagonism of cadmium and alloxan-induced hyperglycemia in rats by Trigonella foenum graecum.

This study was stimulated by popular belief that Trigonella foenum graecum has antidiabetic activity in which the hypoglycemic effect has been confirmed by several investigators. However, the mode of action appears to be unclear. To gain some insight, the stems and leaves of the plant as well as the known active seeds were extracted at room temperature (ca 20 C) for three days with water or acetone and by soxhlet 70 C, and tested by oral administration to rats. Acetone and CC14 extracts before use, were evaporated below 30 C under vacuo, and the residue dissolved in distilled water containing Tween 80. Hypoglycemic activity of these extracts were tested on 20 hour fasted normal, alloxan and cadmium treated rats. The latter has been shown to cause hyperglycemia by releasing epinephrine in intact rats and inhibiting insulin release in the isolated perfused rat pancreas. Results showed that with seeds the CC14, soxhlet acetone extracts were inactive in normal animals as were the water and acetone extracts of stems and leaves. These observations may be compared with room temperature acetone extraction of seeds which exhibited what appeared to be dose related hypoglycemic effects. The hyperglycemia induced by cadmium or alloxan was antagonized by room temperature acetone seed or stem and leaves extracts. Tentative interpretation of the above results, are that Trigonella acetone extract appears to act, at least in part, at the cellular level to produce its hypoglycemic effects on normal rats or those as treated with cadmium or alloxan.

Implications and applications of recent research on feminine development.

The traditional feminine role pattern is no longer adaptive and functional for many women, because of pressures for change associated with such components of the social climate as the lengthening life span and concern about the population explosion. It is no longer physically possible nor considered socially valuable to spend a lifetime bearing and rearing children, even for those women who desire to do so. Thus the prospect or actuality of defining one's life by the wife-and-mother role creates anxiety and anger, which is increased by the awareness that society pays only lip service to so-called "feminine" qualities and behaviors, reserving power and prestige for those who achieve high status in the world of work. Clearly women need alternate bases of gratification and identity. However, these involve interconnected changes that are often painful and that require understanding and support from others which has been slow in coming. The general purpose of this paper is to provide evidence that changes in the feminine role pattern are a matter of urgency and will be beneficial to both sexes.

A profile of cardiovascular disease in northern Ontario: public health planning implications.

Cardiovascular disease (CVD) is a leading cause of death in Northern Ontario and therefore considered an important issue. To this end, this paper examines CVD trends in Northern Ontario and the prevalence of known risk factors that give an insight into these trends. Ontario Health Survey 1990, Ontario Health Survey 1996, Canadian Institute for Health Information (1990-95) and Vital Statistics (1990-95) were examined. It was determined that CVD rates in Northern Ontario significantly exceeded those of the province. Further, high prevalence of modifiable risk factors, such as smoking, fat intake, physical inactivity and obesity are all experienced in Northern Ontario when compared to the province. Planning implications, as they relate to collaboration, delivery of services, determinants of health, multiple risk factors and monitoring and evaluation are also discussed.
