Improvements in children’s health: Does inequality matter?

The literature on the contributions to poverty reduction of average improvements in living standards vs. distributional changes uses only one measure of well-being – income or expenditure. Given that poverty is defined by deprivation over different dimensions, we explore the role of average improvements and distributional changes in children’s health and nutrition using the height of young children as our measure of well-being. Similar to the income literature, we find that shifts in the mean level of heights, not changes in distribution, account for most improvements in heights. Unlike the literature on income inequality, however, there is a positive association between improvements in average heights and reduced dispersion of those heights.

Increasing breastfeeding rates among African-American women enrolled in the Special Supplemental Nutrition Program for Women,Infants, and Children: application of Social Cognitive Theory

Breastfeeding offers tremendous health benefits to both child and mother. In spite of these many benefits, current rates of breastfeeding initiation, duration, and exclusivity among African-American women enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) are lower than rates of other ethnic groups. The decision to breastfeed is complicated, and strategies are needed to increase breastfeeding rates among these women. Social Cognitive Theory (SCT) offers hope for understanding these complicated decisions and for developing strategies to overcome this problem. The purpose of this paper is to explore the literature and develop strategies based on SCT to increase breastfeeding among African-American women enrolled in WIC.

鱼类早期生活史的营养与摄食

鱼类早期生活史可划分为胚胎期、仔鱼期和稚鱼期,其营养包括内源性、外源性和混合性三种类型。仔鱼必须在卵黄耗尽前的短时间内建立起外源性摄食,否则,便进入饥饿期。仔鱼的初次摄食率和摄食强度均取决于仔鱼的摄食效率,并随着日龄的增加而增加。摄食节律主要受光照强度的影响。仔鱼对饵料的选择随着日龄的增加而变化,同时与饵料的大小、种类、密度等因素有关。     

Unequal foodwork: Situating the sociology of feeding within diet and nutrition disparities

Widespread inequities in diet and nutrition present a pressing public health problem. Sociologists working to illuminate the causes and contours of these inequities often center the role of family foodwork, or the multifaceted domestic labor that supports eating, including planning and preparing meals. Mounting sociological scholarship on foodwork considers how food's meanings are socially patterned to reflect broader social structures, ideologies and institutions that influence their manifestation and families' resources to enact them. Here, we present three core contributions from the sociology of foodwork that can advance essential transdisciplinary conversations around nutrition disparities as well as efforts to tackle these disparities. We lay out how (1) family foodwork is historically rooted in broader structures of capitalist exploitation and women's subordination, and today remains gendered through normative discourses equating “good” feeding with “good” mothering; (2) the moralization of foodwork is buttressed by an ideological context idealizing homecooked meals and lamenting foodwork's decline, and; (3) foodwork—and societal evaluations of it—are shaped and stratified by intersecting gendered, classed, and racial inequalities. After reviewing each contribution and its importance for addressing nutrition inequities, we conclude by advocating for a closer conversation across disciplines and highlighting important future directions for sociologists.

Attention-deficit hyperactivity disorder symptomatology,binge eating disorder symptomatology,and body mass index among college students

Abstract

Objective: To explore the relationship between symptoms of attention-deficit hyperactivity disorder (ADHD), symptoms of binge eating disorder, and body mass index (BMI) among students at a southern university. Participants: Two hundred seventy-seven college students. Methods: Between January 31, 2013 and March 27, 2013, participants completed the Adult ADHD Self-Report Scale (ASRS) Screener and the Binge Eating Scale (BES) in addition to permitting researchers to measure their height and weight. Results: Higher ASRS scores, higher BMIs, and lower BES scores were observed among men. Among both men and women, BES scores were positively correlated with BMI and ASRS scores; however, the correlation between ASRS and BMI was not significant. Conclusion: Binge eating disorder symptomatology was associated with increased ADHD symptomatology and a higher BMI among both men and women. Among students presenting with obesity or ADHD, screening for binge eating may assist with the identification of problematic eating behaviors.     

The role of evidence in nutrition policy‐making in Ethiopia: Institutional structures and issue framing

Malnutrition is the single greatest contributor to the global burden of morbidity and mortality, with most cases arising in low‐ and middle‐income countries. However, the multi‐sectoral nature of nutrition policy‐making adds considerable complexity to the implementation of effective programmes. This raises questions about why or how relevant policy change can come about within different country settings. This article examines multi‐sectoral nutrition policy‐making from the health sector perspective, specifically focusing on different sectoral perspectives and the role and use of evidence within this. Ethiopia provides a unique example of the challenging nature of multi‐sectoral nutrition policy‐making, even with a strong co‐ordinating infrastructure. In December 2014 we undertook 23 in‐depth semi‐structured interviews with stakeholders from key health sector organizations, along with a related documentary analysis. Participants represented a diverse range of perspectives, including government representatives, policy stakeholders, aid providers from multi‐lateral organizations and academic researchers. Our respondents described how nutrition framing in Ethiopia is changing, with greater consideration of overweight, obesity and non‐communicable diseases, as well as undernutrition and micronutrient deficiencies. However, overweight‐ and obesity‐related concerns are still less evident in key documents. Some health actors described the challenge of enacting structural policy changes when doing so requires engagement from the agriculture sector. While multi‐sectoral plans and infrastructure to address malnutrition are in place, respondents suggested that the mandate for addressing nutrition resting with the health sector was reinforced by the nature of evidence collected. This study of nutrition policy‐making in Ethiopia highlights the complex interaction of evidence within different conceptualisations of policy problems and responses. Despite Ethiopia's strategic framework and its progress in achieving terms of nutrition targets, it shares the challenge of countries elsewhere in addressing nutrition as a multi‐sectoral issue.     

Multi‐sectoral collaboration for improved nutrition: The problems and prospects of implementation in Ethiopia

Implementing nutrition initiatives through multi‐sectoral collaboration is challenging. This qualitative study explores these challenges in two regions of Ethiopia, through interviews with development staff at lower administrative levels. Respondents identified structural and attitudinal causes of undernutrition. The health sector was perceived to have primary responsibility to address nutrition. The Women's Affairs office had a lesser role than expected. Agricultural officers still saw their primary mandate as increasing cereal production. Cross‐sectoral collaboration was stronger in addressing short‐term food crises rather than chronic undernutrition. There is a need to build a shared understanding of the causes of undernutrition, including the many constraints faced by resource‐poor households, to provide more resources for implementation and to adopt a more gendered focus.
