The influence of active coping and perceived stress on health disparities in a multi-ethnic low income sample

<p>Abstract</p> <p>Background</p> <p>Extensive research has shown that ethnic health disparities are prevalent and many psychological and social factors influence health disparities. Understanding what factors influence health disparities and how to eliminate health disparities has become a major research objective. The purpose of this study was to examine the impact of coping style, stress, socioeconomic status (SES), and discrimination on health disparities in a large urban multi-ethnic sample.</p> <p>Methods</p> <p>Data from 894 participants were collected via telephone interviews. Independent variables included: coping style, SES, sex, perceived stress, and perceived discrimination. Dependent variables included self-rated general and oral health status. Data analysis included multiple linear regression modeling.</p> <p>Results</p> <p>Coping style was related to oral health for Blacks (B = .23, p < .05) and for Whites there was a significant interaction (B = -.59, p < .05) between coping style and SES for oral health. For Blacks, active coping was associated with better self-reported health. For Whites, low active coping coupled with low SES was significantly associated with worse oral health. Coping style was not significantly related to general health. Higher perceived stress was a significant correlate of poorer general health for all ethnoracial groups and poorer oral health for Hispanics and Blacks. SES was directly related to general health for Hispanics (.B = .27, p < .05) and Whites (B = .23, p < .05) but this relationship was mediated by perceived stress.</p> <p>Conclusion</p> <p>Our results indicate that perceived stress is a critical component in understanding health outcomes for all ethnoracial groups. While SES related significantly to general health for Whites and Hispanics, this relationship was mediated by perceived stress. Active coping was associated only with oral health.</p

Not AvailableSeeds from middle and stylar fruit segments showed superior performance in terms of seed yield and quality in chosen two cucumber varieties (Pusa Barkha and Pusa Uday) under both open field (E1) and protected (E2) environments, during 2019-20, at ICAR-Indian Agricultural Research Institute, New Delhi. Besides, both seed quality and yield were superior under protected environment (E2). This may be due to temporal and spatial advantage of stylar segment in receiving the vigorous pollen and garnering higher food accumulates (protein, sugar, starch and oil) than peduncular segment; thus, higher probability of seed setting. Higher dehydrogenases, antioxidants (SOD, CAT & POX) and lower ROS (H2O2 & O2 ·-), electrical conductance, TSS and TSP (seed leachates) from middle and stylar segment of fruit indicated the better physical and physiological soundness of seed. The seeds from peduncular segment lagged behind in development and maturation, showed higher dormancy. Therefore, to obtain optimum seed quality in cucumber, seed should be harvested from middle and stylar segments of fruit.Not Availabl

Not AvailableOnion seed crop is infected with several pest and diseases which reduce the seed yield and quality. The present study explores the feasibility of using polymer as an efficient delivery system for seed-protectant chemicals during onion seed production. Polymer coating prolonged the release of pesticides. After 30 DAP, 557% and 1087% higher retention of fungicide and insecticide was observed in polymer coated bulbs over traditional method of bulb treatment. Onion bulb coating with polymer and 0.15 % fipronil + 0.25 % (carbendazim + mancozeb) showed significantly higher values for seed yield attributes viz. productive scapes/plant (5.56), lower percent lodged scapes (21.16), seed yield/ plant (21.15 g) and seed quality attributes in comparison to control and traditional method of bulb treatment. Lowest percent disease index (36.39) was recorded in treatment- polymer coating + 0.15 % fipronil + 0.25 % (carbendazim + mancozeb) and lowest number of thrips/plant (5.14) was recorded in bulbs coated with polymer + 0.15 % fipronil + 500 ppm streptocyclin. Treating of onion bulbs with polymer is beneficial in increasing the efficacy of the applied pesticides, reducing the incidence of pest and diseases and enhancing seed yield and quality.Not Availabl

Not AvailableThe effect of foliar sprays of plant growth regulators (PGRs), viz. NAA (10, 15 and 20 ppm), GA(3) (50, 75 and 100 ppm) and kinetin (10, 15 and 20 ppm) at 25 and 35 DAS was evaluated on growth, yield and seed quality attributes in garden pea (Pisum sativum var Hortense) cv. Pusa Pragati under field condition. Plant morphology was affected by spray of the three PGRs at vegetative stage. Plant height increased with increase in concentration of GA(3) and kinetin, albeit NAA. However, GA(3) did not influence the number of primary branches/plant, which were significantly increased by kinetin and NAA. GA(3) had a profound effect on hastening the initiation of flowering by 3-5 days over water sprayed control, whereas other plant growth regulators did not affect the days to flowering. The seed quality parameters did not increase significantly on increasing the concentration of PGRs except seedling length and vigour.Not Availabl
