Values of hypercompetitive and personal development competitive individuals.

The value systems of hypercompetitive and personal development competitive individuals were examined in a sample of university undergraduates. As expected, people higher in hypercompetitiveness and in personal development competitiveness were both more likely to endorse values related to self-contained individualism such as achievement, hedonism, and a striving for an exciting and challenging life, but only hypercompetitives endorsed the value of power and control over others. Moreover, the data indicated that people higher in personal development competitiveness were more prone to endorse values related to ensembled individualism. In particular, they strongly endorsed values associated with social concern, that is, with caring about the well-being of others and with treating them with respect and as equals, whereas hypercompetitives expressed a lack of such concern. Discussion centered on the socialization process and how it can foster the development of different competitive orientations.

A fish oil diet inhibits colon cancer in mice.

High-fat, high-cholesterol diets have been linked to colon cancer in both epidemiological and animal studies. Saturated and N-6 polyunsaturated fats have both been implicated as playing causative roles. Epidemiological studies have shown a reduced colon cancer incidence in populations consuming a large quantity of N-3 polyunsaturated fat. This study asked whether N-3 polyunsaturated fat found in fish oil would also be associated with reduced colon cancer in animal studies. 1,2-Dimethylhydrazine was used to induce colon cancer in mice fed three high-fat, high-cholesterol diets (beef tallow, safflower oil, and fish oil) and one low-fat, cholesterol-free diet (soybean oil). Colon adenocarcinomas developed in 55% of mice fed tallow, 48% of those fed low-fat diets, 33% of those fed safflower oil, and 18% of those fed fish oil (p less than 0.05). Tumors per animal were also greatest in mice fed tallow and fewest in those fed fish oil (p less than 0.05). Plasma cholesterol levels were significantly higher in mice fed tallow than in mice fed fish oil, but this did not show any association with tumors. Plasma triglyceride levels were not significantly different among groups but were strongly correlated with colon cancers (r = 0.90, p less than 0.025). In both plasma and colon mucosa cells, saturated fat levels were similar. Monounsaturated fat was highest in plasma of mice fed tallow and correlated strongly with colon cancers (r = 0.84, p less than 0.005). N-6 polyunsaturated fat was highest in plasma and colon mucosa cells of both mice fed safflower oil and those fed low-fat (soybean oil) diet, but there was no association with tumors. N-3 polyunsaturated fat was highest in plasma and colon mucosa cells of mice fed fish oil and showed a negative association with tumors (r = -0.57, p less than 0.05). Thus, in this model of colon cancer, a diet high in fish oil was associated with less colon cancer. Monounsaturated fat was most strongly correlated with tumors. This study suggests monounsaturated fat promotes colon tumors and N-3 polyunsaturated fat inhibits colon tumors.

Family planning for the mentally handicapped.

PIP: Although family planning services have grown throughout much of the world, organized efforts to incorporate voluntary fertility-regulating resources into specialized service programs for the mentally handicapped have been sparse. With the growing shift from custodial and segregative institutionalization of the mentally ill and the mentally retarded to early discharge and community maintenance, there are greater opportunities for heteroxexual relationships and a concomitant risk of unintended pregnancies. While the birth rate among Western societies has decreased since the introduction of modern methods of contraception, among the mentally handicapped, it has increased. A review of European and North American publications reflects an increasing awareness of the problem of providing family planning services to mentally ill and mentally retarded people in a more active manner. Mental health specialists and those who work with the handicapped must be made more familiar with the needs of their patients in regard to family planning and they must develop the sensitivity needed to help the mentally handicapped search for a resolution to their sexual problems.^ieng
