Background: Although health inequality between young adult women and men has been strikingly evident in symptoms of ill health, we found no studies examining these inequalities with a focus on positive health and performance.Objective: The aim of the present study was to examine possible inequalities between young adult women and men in a combined assessment of positive health and health-related performance.Methods: Women and men aged 18 to 25 years studying medicine or computer science at 6 colleges/universities in 5 cities in Sweden were recruited for this study. All respondents answered a Web-based questionnaire regarding health, health-related performance, information and communication technology exposure, mood, and individual factors. A combined assessment of excellent health and health-related performance (EHHP) was defined and tested. Prevalence ratios (PRs) with 95% CIs of EHHP were calculated separately for female and male respondents. To assess potential determinants of EHHP, differences in the relationships between EHHP and the explanatory factors were compared for both sexes.Results: In a study group of young adult students consisting of 1046 women and 1312 men, women were less likely than men to have EHHP (PR 0.90 [95% CI, 0.83–0.98]). This inequality was even stronger within each course of study (medicine or computer science). Health-related factors showed similar patterns of relationship to EHHP for women and men; however, the strength of these relationships differed between the sexes. Logical relationships were observed between EHHP and almost all of the symptoms as well as between EHHP, the mood index, and health-related behavior.Conclusions: The well-known inequality in symptoms of ill health between young adult women and men was prevalent even in a combined assessment of positive health and health-related performance. That this inequality was prevalent in a relatively homogeneous sample of young adults indicates the importance of gender-based psychological and psychosocial factors beyond the more well-known structural gender-differentiating factors of vertical and horizontal segregation and disproportional responsibilities for domestic work. It may therefore be essential to emphasize these gender-based psychological and psychosocial factors when designing future studies and health promotion programs. 相似文献

Coercion may play an important role in compelling young women to engage in sexual intercourse at an early age. With a decline in age at first intercourse and increased reporting of coercive first sex, concerns of adverse reproductive health outcomes such as unintended pregnancy and sexually transmitted infections (STIs), including HIV, have become important issues, particularly in the context of a high HIV prevalence. This paper uses data collected in 2001 from the second round of a longitudinal study of 1130 sexually experienced young women in KwaZulu-Natal to investigate the relationship between coerced first intercourse and selected reproductive health outcomes and behaviours. Nearly 46% of all sexually experienced young women had reported that their first sexual encounter had been coerced. Young women who reported being coerced at first sex were significantly more likely to be Black and living in an urban area. Those who had been coerced at first sex were also more likely to report having had an STI and having experienced unintended pregnancy, than those who had not been coerced at first sex. Coercion at first sex is an important social and public health problem that has a serious impact on the reproductive health and behaviours of young women. Interventions should directly address the issue of sexual coercion by ensuring young women are aware of their reproductive rights. 相似文献

A large survey by the Ministry of Agriculture, Fisheries and Food of people aged 15 to 25 showed that the women, and especially the participants "on a diet" or "watching their weight," generally had iron intakes well below the recommended daily allowance. Reduced iron intake appeared to result from diets of reduced iron concentration as well as from energy restriction. Further research is needed to establish whether this population is compromised or whether the current recommended daily allowances are unnecessarily high. 相似文献

Aberrations in global LINE-1 DNA methylation have been related to risk of cancer and cardiovascular disease. Micronutrients including methyl-donors and retinoids are involved in DNA methylation pathways. We investigated associations of micronutrient status and LINE-1 methylation in a cross-sectional study of school-age children from Bogotá, Colombia. Methylation of LINE-1 repetitive elements was quantified in 568 children 5–12 years of age using pyrosequencing technology. We examined the association of LINE-1 methylation with erythrocyte folate, plasma vitamin B12, vitamin A ferritin (an indicator of iron status) and serum zinc concentrations using multivariable linear regression. We also considered associations of LINE-1 methylation with socio-demographic and anthropometric characteristics. Mean (± SD) LINE-1 methylation was 80.25 (± 0.65) percentage of 5-mC (%5-mC). LINE-1 methylation was inversely related to plasma vitamin A. After adjustment for potential confounders, children with retinol levels higher than or equal to 1.05 µmol/L showed 0.19% 5-mC lower LINE-1 methylation than children with retinol levels lower than 0.70 µmol/L. LINE-1 methylation was also inversely associated with C-reactive protein, a marker of chronic inflammation, and female sex. We identified positive associations of maternal body mass index and socioeconomic status with LINE-1 methylation. These associations were not significantly different by sex. Whether modification of these exposures during school-age years leads to changes in global DNA methylation warrants further investigation. 相似文献

A population-based hospital survey of 3628 women in the postpartum period was conducted in the Ottawa-Carleton region in 1983 to determine the prevalence of smoking before and during pregnancy, the demographic and socioeconomic characteristics of women who smoke during pregnancy and the use of health care services by these women. Of the 3628 women 91% completed a full-length questionnaire and 4% completed a shorter questionnaire. Before pregnancy 37.4% of the women smoked cigarettes. Overall, 61.1% of the smokers changed their smoking habit: 31.1% stopped, 28.1% decreased the amount smoked and 2.0% increased the amount smoked. Two thirds of the women who stopped smoking did so as soon as they realized they were pregnant. Over 50% of teenagers, single women, women living common-law and women with less than a grade 11 education smoked after the 3rd month of pregnancy. The physician is in an ideal position to identify as soon as possible pregnant women who smoke and to initiate a health education program. Only a few women who smoked during pregnancy attended early prenatal classes. Physicians and class organizers must work to improve this situation if such classes are to have an impact on smoking during pregnancy. 相似文献

Micronutrient deficiencies are widespread in developing countries, particularly in remote communities such as mobile pastoralists. The nutritional and vitamin A status of this population is not well-documented in Chad. This study assessed serum retinol levels among women and children under five-year-old in nomadic and semi-nomadic pastoralist and rural-settled communities, who are similarly exposed to risk factors such as gastrointestinal parasitic infection, anaemia and emaciation. The novel method of portable fluorometry was used for the first time to measure β-carotene and retinol levels in a pastoral nomadic area. Moderate level blood retinol deficiency (<0.7?μmol/L) was observed in 5% (CI 1-11) of nomadic, 29% (CI 13-45) of semi-nomadic and 22% (CI 8-35) of sedentary women. In children, 1% (CI 0.1-4), 17% (CI 9-25) and 28% (CI 18-39), respectively, had moderate level blood retinol deficiency. In nomadic communities, women and children had blood retinol levels close to normal. Deficiency of retinol was strongly linked with lifestyle (nomadic, semi-nomadic and settled) among women and lifestyle and age among children. The results support an ecological linkage between human retinol levels and livestock milk retinol. This study shows the feasibility of portable retinol and β-carotene measurement in human blood as well as human and animal milk under remote field conditions, but the approach requires further validation. 相似文献

Background: The number of women infected with human papillomavirus (HPV) and the distribution of the HPV genotypes vary across populations and with age. Objective: To determine the prevalence and genotype distribution of HPV in young married women aged 16–24 years. Methods: 1300 women residing in an urban slum in Delhi donated samples of exfoliated cervical cells that were collected by the Digene® kit and tested for the presence of HPV DNA by two techniques in parallel, i.e., PCR using PGMY consensus primers for all HPV types and the Digene HPV test (Hybrid Capture 2 (HC2) Probe B for high-risk (hr) types. Genotyping was done on all HPV positive samples using the Roche reverse line blot assay. Results: HPV infection was detected in 91/1300 (7%) samples by PCR and 110/1300 (8.4%) samples by HC2. Genotyping identified 20 high-risk and 11 low-risk types. HPV16 was the commonest high-risk type (3%) followed by HPV52 (1.2%) and HPV51 (0.8%). Among low-risk types, HPV62 was the commonest (0.8%), followed by HPV84 and HPV89 (0.5% each). Multiple infections were found in 3% of the HPV positive samples. Conclusion: A wide spectrum of HPV genotypes is seen in this young population. Knowledge about HPV types prevalent in communities in different regions of India would be useful in devising the optimum strategy for cervical cancer prevention. 相似文献

The use of genetically modified (GM) insects for control of human disease can be consistent with common ethical norms of international society to reduce human suffering. This paper considers a range of ethical issues including animal rights, informed consent, community consensus and environmental viewpoints. Each community needs to decide its own priorities for methodology of disease policy guidance for ethical genetic engineering, and to negotiate with neighbouring countries. The approach to genetically modify insects raises few intrinsic ethical issues; however, important environmental and human health concerns need to be assessed before release of any GM insects. The policy that each community adopts should be the product of open dialogue involving all sectors of society. It can be expected that this process will take years and not all communities will endorse genetic control approaches to insect vectors. 相似文献

Background
Diarrhea remains one of the leading causes of morbidity and mortality among children under 5 years of age, but in many low and middle-income countries where vital registration data are lacking, updated estimates with regard to the proportion of deaths attributable to diarrhea are needed.Methods
We conducted a systematic literature review to identify studies reporting diarrhea proportionate mortality for children 1–59 mo of age published between 1980 and 2009. Using the published proportionate mortality estimates and country level covariates we constructed a logistic regression model to estimate country and regional level proportionate mortality and estimated uncertainty bounds using Monte-Carlo simulations.Findings
We identified more than 90 verbal autopsy studies from around the world to contribute data to a single-cause model. We estimated diarrhea proportionate mortality for 84 countries in 6 regions and found diarrhea to account for between 10.0% of deaths in the Americas to 31.3% of deaths in the South-east Asian region.Discussion
Diarrhea remains a leading cause of death for children 1–59 mo of age. Published literature can be used to create a single-cause mortality disease model to estimate mortality for countries lacking vital registration data. 相似文献20.
Public health communication campaigns have been credited with helping raise awareness of risk from chronic illness and new infectious diseases and with helping promote the adoption of recommended treatment regimens. Yet many aspects of public health communication interventions have escaped the scrutiny of ethical discussions. With the transference of successful commercial marketing communication tactics to the realm of public health, consideration of ethical issues becomes an essential component in the development and application of public health strategies. Ethical issues in public health communication are explored as they relate to eight topics: 'targeting' and 'tailoring' public health messages to particular population segments; obtaining the equivalence of informed consent; the use of persuasive communication tactics; messages on responsibility and culpability; messages that apply to harm reduction; and three types of unintended adverse effects associated with public health communication activities that may label and stigmatise, expand social gaps, and promote health as a value. We suggest that an ethical analysis should be applied to each phase of the public health communication process in order to identify ethical dilemmas that may appear subtle, yet reflect important concerns regarding potential effects of public health communication interventions on individuals and society as a whole. 相似文献
