Inter-relações entre minerais no solo, plantas forrageiras e tecido animal 3. Manganês, ferro e cobalto
An experiment was conducted with samples from six farms in northern Mato Grosso, Brazil, to study the interrelationships among levels of minerals in soil and forage and animal tissues during the wet and dry seasons of the year. Soil extractable Mn levels were slightly low (6 and 14 ppm) in two farms, but adequated over 20 ppm in the other four farms. Forage Mn levels were sufficient to meet the requirements of grazing cattle in all six farms. However, liver Mn was deficient on five of the six farms, and during the wet season there was more deficiency than during the dry one. Soil extractable Fe was slightly low for production of some crops in two of the farms, but adequate (over 20 ppm), on the other four farms. High forage Fe on all six farms was sufficient to meet the requirement of grazing beef cattle. Liver Fe levels were normal in all six farms. Soil extractable Co was adequate in the farms 1,3 and 4, and deficient in the other three. Forage Co was adequate in the farms that had also adequate soil Co, and deficient where soil Co was deficient. Liver cobalt was at normal level in all six farms due to the high cobalt supplementation. Liver Co means were lower during the wet season than during the dry season.Fez-se um estudo das deficiências minerais em seis fazendas localizadas ao norte do Estado de Mato Grosso, tendo sido amostrados os solos, plantas forrageiras e tecido animal, coletados durante as estações seca e chuvosa. As análises de Mn indicam que, das seis fazendas estudadas, duas tinham níveis de Mn no solo considerados baixos, 6 e 14 ppm; as outras quatro apresentaram níveis adequados, acima de 20 ppm. Os níveis de Mn nas forrageiras eram suficientes para atender às exigências dos bovinos, em todas as seis fazendas, nas duas épocas estudadas. Entretanto, os níveis de Mn no fígado dos animais foram deficientes em cinco das seis fazendas estudadas, e na estação chuvosa, a deficiência era mais generalizada do que no período seco. As análises de Fe no solo mostraram que duas fazendas apresentaram níveis ligeiramente baixos para algumas das forrageiras, mas as outras quatro tinham níveis médios adequados, acima de 20 ppm. Os níveis de Fe nas forrageiras e no fígado, em todas as seis fazendas, foram considerados adequados para bovinos de corte. Os solos da fazenda 1, 3 e 4, mostraram teores adequados de Co; entretanto as demais fazendas possuíam solos deficientes. Apenas as forrageiras das fazendas que tinham solos ricos em Co, possuíam esse mineral em quantidade suficiente para atender às exigências nutricionais dos animais. Em todas as fazendas, os animais apresentaram níveis adequados de Co. As médias de Co no fígado foram mais baixas na estação chuvosa do que na estação seca
Health Economics in Public Health
BACKGROUND: Economic analysis is an important tool in deciding how to allocate scarce public health resources; however, there is currently a dearth of such analysis by public health researchers.
METHODS: Public health researchers and practitioners were surveyed to determine their current use of health economics and to identify barriers to use as well as potential strategies to decrease those barriers in order to allow them to more effectively incorporate economic analyses into their work. Data collected from five focus groups informed survey development. The survey included a demographic section and 14 multi-part questions. Participants were recruited in 2006 from three national public health organizations through e-mail; 294 academicians, practitioners, and community representatives answered the survey.
RESULTS: Survey data were analyzed in 2007. Despite an expressed belief in the importance of health economics, more than half of the respondents reported very little or no current use of health economics in their work. Of those using health economics, cost-benefit and cost-effectiveness analysis and determination of public health costs were cited as the measures used most frequently. The most important barriers were lack of expertise, funding, time, tools, and data, as well as discomfort with economic theory. The resource deemed most important to using health economics was collaboration with economists or those with economic training. Respondents indicated a desire to learn more about health economics and tools for performing economic analysis.
CONCLUSIONS: Given the importance of incorporating economic analysis into public health interventions, and the desire of survey respondents for more collaboration with health economists, opportunities for such collaborations should be increased
The perceived influence of cost-offset community-supported agriculture on food access among low-income families
Objective To examine perspectives on food access among low-income families participating in a cost-offset community-supported agriculture (CO-CSA) programme.Design Farm Fresh Foods for Healthy Kids (F3HK) is a multicentre randomized intervention trial assessing the effect of CO-CSA on dietary intake and quality among children from low-income families. Focus groups were conducted at the end of the first CO-CSA season. Participants were interviewed about programme experiences, framed by five dimensions of food access: Availability, accessibility, affordability, acceptability and accommodation. Transcribed data were coded on these dimensions plus emergent themes.Setting Nine communities in the US states of New York, North Carolina, Washington and Vermont.Subjects Fifty-Three F3HK adults with children.Results CSA models were structured by partner farms. Produce quantity was abundant; however, availability was enhanced for participants who were able to select their own produce items. Flexible CSA pick-up times and locations made produce pick-up more accessible. Despite being affordable to most, payment timing was a barrier for some. Unfamiliar foods and quick spoilage hindered acceptability through challenging meal planning, despite accommodations that included preparation advice.Conclusions Although CO-CSA may facilitate increased access to fruits and vegetables for low-income families, perceptions of positive diet change may be limited by the ability to incorporate share pick-up into regular travel patterns and meal planning. Food waste concerns may be particularly acute for families with constrained resources. Future research should examine whether CO-CSA with flexible logistics and produce self-selection are sustainable for low-income families and CSA farms
Haplotype Structure of FSHB, the Beta-Subunit Gene for Fertility-Associated Follicle-Stimulating Hormone: Possible Influence of Balancing Selection
Follicle-stimulating hormone (FSH) is essential for human reproduction. The unique functions of this hormone are provided by the FSH receptor-binding beta-subunit encoded by the FSHB gene. Resequencing and genotyping of FSHB in three European, two Asian and one African population, as well as in the great apes (chimpanzee, gorilla, orangutan), revealed low diversity and significant excess of polymorphisms with intermediate frequency alleles. Statistical tests for FSHB showed deviations from neutrality in all populations suggesting a possible effect of balancing selection. Two core haplotypes were identified (carried by 76-96.6% of each population's sample), the sequences of which are clearly separated from each other. As fertility most directly affects an organism's fitness, the carriers of these haplotypes have apparently had more success in human history to contribute to the next generation. There is a preliminary observation suggesting that the second most frequent FSHB haplotype may be associated with rapid conception success in females. Interestingly, the same haplotype is related to an ancestral FSHB variant shared with the ancestor of the great apes. The determination of the functional consequence of the two core FSHB variants may have implications for understanding and regulating human fertility, as well as in assisting infertility treatments
Perceptions of the Community Food Environment and Related Influences on Food Choice Among Midlife Women Residing in Rural and Urban Areas: A Qualitative Analysis
Introduction—Qualitative research on food choice has rarely focused on individuals’ perceptions of the community food environment. Women remain gatekeepers of the family diet and food purchasing. Therefore we assessed midlife, Southern women's perceptions of the food environment. Related influences on food choices at work and at home were also examined. Methods—We recruited 28 low- and moderate-income, midlife (37-67 years) women from rural and urban areas of southeastern North Carolina, using typical case and snowball sampling. They responded to questions about multilevel influences on food choice in semi-structured, in-depth interviews. Results—Women perceived differences between urban and rural food environments, with rural areas having fewer supermarkets and fast food restaurants compared to urban areas, which had fewer produce stands. Workplace food choices were affected by the social environment (co-workers), personal health concerns, and the surrounding food environment. Food chosen at home was primarily influenced by family members, health concerns, and convenient food sources. Discussion—While future studies should explore findings in more representative populations, potential intervention strategies can be inferred, including emphasizing healthful aspects of the food environment. Intervention and advocacy efforts are needed to improve aspects of the food environment that make healthy choices difficult. Originally published in Women & Health Vol. 49, No. 2-3, 2009
Association of Adverse Childhood Experiences with Non-Suicidal Self-Injury and Suicidality: Baseline Survey of the Chinese Adolescent Health Growth Cohort
Many studies have identified that adverse childhood experiences (ACEs) are associated with non-suicidal self-injury (NSSI) and suicidality. However, most studies have been restricted to a few types of ACEs. This study aims to investigate the association of 13 common types of ACEs with NSSI, suicidal ideation (SI), and suicide attempts (SA), as well as the mediation of depressive and anxiety symptoms therein. A total of 1771 (994 male, 777 female) students aged 11–16 (12.9 ± 0.6) years who participated in the baseline survey of the Chinese Adolescent Health Growth Cohort study were included in the analysis. ACEs, including childhood maltreatment, other common forms of ACEs, and smoking, were measured via the Chinese version of the Child Trauma Questionnaire (CTQ) and a series of valid questionnaires that were derived from previous studies. NSSI was measured using the Chinese version of the Functional Assessment of Self-mutilation. SI and SA were measured using questions derived from the Global School Based Student Health Survey. Depressive symptoms were measured via the Chinese version of the Center for Epidemiologic Studies Depression Scale, and anxiety symptoms were measured via the General Anxiety Disorder-7. Of the included participants, 92.0% reported one or more category of ACEs. Smoking, parent–child separation, emotional abuse, physical abuse, and being bullied were positively associated with NSSI; smoking, parent–child separation, emotional abuse, physical abuse, emotional neglect, and being bullied were positively associated with SI; smoking, emotional abuse, and being bullied were positively associated with SA. The associations of ACEs with NSSI, SI, and SA were each partially or completely mediated through depressive and anxiety symptoms. Children and adolescents who had experiences of smoking, physical abuse, and being bullied during childhood are consistently and independently associated with NSSI and suicidality, and these associations may be largely mediated through depressive and anxiety symptoms. In conclusion, not all the types of ACEs are independently associated with NSSI, and suicidality and other associations may mediate through depressive and anxiety symptoms. Target interventions for adolescents’ NSSI and suicidality should focus on those who have a history of ACEs and depressive and anxiety symptoms
Maternal participation in a nutrition education program in Uganda is associated with improved infant and young child feeding practices and feeding knowledge: a post-program comparison study
Abstract Background Cost-effective approaches to improve feeding practices and to reduce undernutrition are needed in low-income countries. Strategies such as nutritional counseling, food supplements, and cash transfers can substantially reduce undernutrition among food-insecure populations. Lipid-based nutrient supplements (LNS) are an increasingly popular strategy for treating and preventing undernutrition and are often delivered with nutrition education. The post-program effects of participation in a LNS-supported supplemental feeding program on Infant and Young Child Feeding (IYCF) practices and caregiver child feeding knowledge are not well understood. The objective of this study was to understand whether children’s diet quality and caregiver nutrition knowledge was improved after participation in such a program. Methods We conducted a post-program comparison group study to compare feeding practices and caregiver nutrition knowledge among mother-child dyads who completed a nutrition education program and a community comparison group in western Uganda. We administered a feeding practices survey and two 24-h dietary recalls to 61 Post-Program (PP) caregivers and children ages 6 to 59 months (mean age = 25.1 months) who participated in a supplemental feeding program (which included growth monitoring, caregiver nutrition education, and LNS) and a Comparison Group (CG) of 61 children and caregivers. PP caregivers were recruited 4 to 8 weeks after program participation ended. We hypothesized that PP caregivers would report better IYCF practices and greater knowledge of key nutrition education messages related to IYCF. Results PP children had higher dietary diversity scores (3.0 vs 2.1, p =0.001) than CG children, and were more fed more frequently (3.0 vs 2.1 times per day, p = 0.001). IYCF indicators were higher in the PP group for minimum meal frequency (44.8% vs. 37.9%), minimum dietary diversity (10.3 vs. 3.4%), iron-rich complementary foods (17.2 vs. 20.7%), and minimally acceptable diet (10.3% vs 3.6%), but differences were non-significant. Caregivers in the PP group demonstrated greater knowledge of healthful IYCF practices. Conclusions Nutrition education can be effective to improve caregiver feeding practices and children’s dietary diversity and the frequency by which they are fed. A 10-week nutrition education and supplemental feeding program appears to provide some benefit to children in terms of dietary diversity and frequency of meals, and caregiver knowledge of feeding 1 to 2 months after program completion. However, children in this rural Ugandan region have diets that are still largely inadequate, highlighting the need for enhanced interventions and policies to promote diverse and appropriate diets for young children in this region. Future follow-up work in LNS-supported programs is recommended to understand how other similar approaches influence children's diet quality after program completion in other contexts
Practice level costs of office-based hypertension performance improvement: The Heart Healthy Lenoir study
Primary care practice leaderswho consider engaging in quality improvement (QI) need to understand the practice level costs incurred when asking staff to take on new tasks. The HeartHealthy Lenoir study is a prospective cohort trial in whichQImethods were used to enhance hypertension (HTN) care and reduce racial disparities in blood pressure control in small rural primary care practices inNorth Carolina. As part of this effort, we performed an activity-based costing analysis to describe the costs incurred to develop, implement, and maintain key tasks. We interviewed 20 practice stakeholders and phone-based health coaches during 2012-2014. We calculated the time invested by individuals to perform each task within each study phase and applied national hourly wages to generate cost estimates. Our descriptive analyses focus on four of themost widely used practices. Activities included time to abstract HTN control data, participate in project meetings, identify patients with uncontrolled HTN, create standardized work, and provide additional health coaching for patients with uncontrolled HTN. Despite practice and staffing differences, the developmental phase costs were similar, ranging from 1, 417. Implementation costs varied more widely as practices took different approaches to identifying patients with uncontrolled HTN. Practice-specific phone health coaching costs ranged from 38, 000. This study adds to the growing literature regarding practice level costs of engaging in systems change. Understanding these costs and balancing them against practice incentives may be helpful as stakeholders make decisions regarding HTN QI
Effectiveness of interventions to promote healthy diet in primary care: systematic review and meta-analysis of randomised controlled trials
Background
A diet rich in fruit, vegetables and dietary fibre and low in fat is associated with reduced risk of chronic disease. This review aimed to estimate the effectiveness of interventions to promote healthy diet for primary prevention among participants attending primary care.<p></p>
Methods
A systematic review of trials using individual or cluster randomisation of interventions delivered in primary care to promote dietary change over 12 months in healthy participants free from chronic disease or defined high risk states. Outcomes were change in fruit and vegetable intake, consumption of total fat and fibre and changes in serum cholesterol concentration.<p></p>
Results
Ten studies were included with 12,414 participants. The design and delivery of interventions were diverse with respect to grounding in behavioural theory and intervention intensity. A meta-analysis of three studies showed an increase in fruit consumption of 0.25 (0.01 to 0.49) servings per day, with an increase in vegetable consumption of 0.25 (0.06 to 0.44) serving per day. A further three studies that reported on fruit and vegetable consumption together showed a pooled increment of 0.50 (0.13 to 0.87) servings per day. The pooled effect on consumption of dietary fibre, from four studies, was estimated to be 1.97 (0.43 to 3.52) gm fibre per day. Data from five studies showed a mean decrease in total fat intake of 5.2% of total energy (1.5 to 8.8%). Data from three studies showed a mean decrease in serum cholesterol of 0.10 (-0.19 to 0.00) mmol/L.<p></p>
Conclusion
Presently-reported interventions to promote healthy diet for primary prevention in primary care, which illustrate a diverse range of intervention methods, may yield small beneficial changes in consumption of fruit, vegetables, fibre and fat over 12 months. The present results do not exclude the possibility that more effective intervention strategies might be developed.<p></p>
