Reproductive inequality in humans and other mammals.

To address claims of human exceptionalism, we determine where humans fit within the greater mammalian distribution of reproductive inequality. We show that humans exhibit lower reproductive skew (i.e., inequality in the number of surviving offspring) among males and smaller sex differences in reproductive skew than most other mammals, while nevertheless falling within the mammalian range. Additionally, female reproductive skew is higher in polygynous human populations than in polygynous nonhumans mammals on average. This patterning of skew can be attributed in part to the prevalence of monogamy in humans compared to the predominance of polygyny in nonhuman mammals, to the limited degree of polygyny in the human societies that practice it, and to the importance of unequally held rival resources to women's fitness. The muted reproductive inequality observed in humans appears to be linked to several unusual characteristics of our species-including high levels of cooperation among males, high dependence on unequally held rival resources, complementarities between maternal and paternal investment, as well as social and legal institutions that enforce monogamous norms.

Cultural Consonance in Food Consumption and Nutrient Intake in Southern Brazil.

Culture influences food consumption and nutrient intake. In this paper we present a new approach in research, examining how knowledge and understanding of food is encoded in cultural models. The degree to which individuals match these shared models in their own consumption patterns is then measured, using the concept of cultural consonance. In research conducted in urban Brazil, the configuration of cultural models of food, and the association of cultural consonance in food with nutrient intake, are moderated by socioeconomic status. The theory and method employed here offers a new approach to the study of culture, food, and nutrient intake.

A decade of rapid change: Biocultural influences on child growth in highland Peru.

OBJECTIVES: In the past decade many areas of Peru have been undergoing extreme environmental, economic, and cultural change. In the highland hamlet of Chugurpampa, La Libertad, climate change has ruined harvests and led to frequent periods of migration to the coast in search of livelihood. This biocultural research examines how the changes could be affecting the growth of children who maintain residence in the highlands. METHODS: Clinical records from the early 2000s were compared to those from the early 2010s. Charts were randomly selected to record anthropometric data, netting a sample of 75 children ages 0-60 months of age. Analysis of covariance was run to compare mean stature, weight, and BMI between cohorts. Percentage of children who fall below the -2 threshold for z-scores for height and weight were compared by age and cohort. RESULTS: A significant secular trend in growth was found, with children born more recently larger than those born a decade before. The effect is most notable in the first year of life, with the growth advantage attenuated by the age of 3 for height and age 4 for weight. While children were unlikely to be stunted from 0 to 3 years of age, 44% of the later cohort were stunted and 11% were underweight from 4 to 5 years of age. CONCLUSIONS: Three possible explanations for the rapid shift are entertained: more time spent on the coast during gestation and early childhood, which may attenuate the effect of hypoxia on child growth; dietary change; and increased use of biomedicine.

How culture shapes the body: cultural consonance and body mass in urban Brazil.

OBJECTIVES: The aim of this article is to develop a model of how culture shapes the body, based on two studies conducted in urban Brazil. METHODS: Research was conducted in 1991 and 2001 in four socioeconomically distinct neighborhoods. First, cultural domain analyses were conducted with samples of key informants. The cultural domains investigated included lifestyle, social support, family life, national identity, and food. Cultural consensus analysis was used to confirm shared knowledge in each domain and to derive measures of cultural consonance. Cultural consonance assesses how closely an individual matches the cultural consensus model for each domain. Second, body composition, cultural consonance, and related variables were assessed in community surveys. Multiple regression analysis was used to examine the association of cultural consonance and body composition, controlling for standard covariates and competing explanatory variables. RESULTS: In 1991, in a survey of 260 individuals, cultural consonance had a curvilinear association with the body mass index that differed for men and women, controlling for sociodemographic and dietary variables. In 2001, in a survey of 267 individuals, cultural consonance had a linear association with abdominal circumference that differed for men and women, controlling for sociodemographic and dietary variables. In general, as cultural consonance increases, body mass index and abdominal circumference decline, more strongly for women than men. CONCLUSIONS: As individuals, in their own beliefs and behaviors, more closely approximate shared cultural models in socially salient domains, body composition also more closely approximates the cultural prototype of the body.

Chestnuts and spring chickens: conflict and change in farmers market ideologies.

The taxonomy of farmers markets requires an update to encompass the expanding range of available options. Also absent from the literature is an appreciation of the connection between market types, ideological stances, social characteristics, and conflict-necessary for understanding the social processes, motivations, and expectations that create a farmers market. Our study of a long-standing farmers market on the verge of municipal revamping aims to unite these interests, with a focus on the diverse demographics and values of the social groups involved. We propose a synthetic two-dimensional scheme to classify U.S. farmers markets. Bourdieu's theory of distinction is instrumental in making sense of the diversity encountered.

Time in the United States and diabetes among Mexican immigrant women: The moderating role of culture.

Mexican immigrants in the U.S. show high incidence of type 2 diabetes, and increased risk is associated with longer duration of residency. This study considers the impact of culture over time for Mexican immigrant women in a southern U.S. city. Using cultural consensus analysis to empirically derive the substance and structure of a cultural model for la buena vida (the good life) among Mexican immigrant women in Birmingham, Alabama, we assess the extent to which respondents are aligned with the model in their everyday lives. This measure of 'cultural consonance' is explored as a moderating variable between length of time living in the U.S. and level of Hemoglobin A1c. Results demonstrate that for those with more time in the U.S., those with lower consonance are more likely to have diabetes, while those who are more aligned with la buena vida are at lower risk.

Age at Arrival and Depression among Mexican Immigrant Women in Alabama: The Moderating Role of Culture.

Mexican-born women in the U.S. are at high risk of depression. While acculturation is the primary analytical framework used to study immigrant mental health, this research suffers from (1) a lack of specificity regarding how cultural models of living and being take shape among migrants converging in new destinations in the U.S., and (2) methods to empirically capture the impact of cultural positioning on individual health outcomes. Instead of relying on proxy measures of age at arrival and time in the U.S. to indicate where an individual is located on the acculturation spectrum, this study uses cultural consensus analysis to derive the substance and structure of a cultural model for la buena vida (the good life) among Mexican immigrant women in Birmingham, Alabama, and then assesses the extent to which respondents are aligned with the model in their everyday lives. This measure of 'cultural consonance' is explored as a moderating variable between age at arrival in the U.S. and number of depressive symptoms. Results demonstrate that for those who arrived at an older age, those with lower consonance are at the highest risk for depression, while those who are more aligned with la buena vida are at lower risk.

Intracultural diversity in food knowledge in southern Brazil.

This research explores the social distribution of food knowledge in Ribeirão Preto, a city in the state of São Paulo, Brazil. Through an analysis of the distribution of individual expertise in regard to the cultural model of food along the dimensions of healthfulness, practicality, and prestige, this research demonstrates that knowledge of the cultural model of food is most strongly shared in the upper class of the city. Qualitative and quantitative ethnographic research suggests that the social patterning of health-related food knowledge in Ribeirão Preto may serve to maintain class distinction.

Are the Undocumented Deserving? Health Workers' Views of Immigrants in Alabama.

Undocumented immigrants are ineligible for many public benefits and often rely on safety-net clinics, such as community health centers, for health care. Using in-depth interviews, we explored attitudes about undocumented immigrants' deservingness of health care among staff and professional health workers (n=31) at two safety-net clinics in Alabama, which passed a restrictive immigration law in 2011. We used content analysis to examine frequently used frames to describe health deservingness. Overall, a total of 27 frames were used by health workers. They most frequently justified their views using frames of medical humanitarianism (i.e., health workers should care for those in need) and equality (i.e., people should not be treated differently from one another). Several respondents used multiple, conflicting frames that simultaneously supported and questioned immigrants' deservingness of care. The diverse ways in which health workers in this sample framed undocumented immigrants' health deservingness may affect provider-patient interactions.

Eating, drinking and being depressed: the social, cultural and psychological context of alcohol consumption and nutrition in a Brazilian community.

Much has been written about the socioeconomic distribution of nutritional status, both in more economically developed, and in developing nations. In general, persons of lower socioeconomic status suffer adverse consequences of poor nutritional status, although these consequences can vary depending on the level of development, i.e. in more developed countries the problem tends to be one of over-nutrition and obesity, while in developing countries the problem tends to be one of under-nutrition and nutritional deficiencies. In this paper, we explore the socioeconomic distribution of dietary intake in a Brazilian city, in an area that in some ways is neither prototypically developed or underdeveloped. The analysis presented here was stimulated by the surprising observation of no socioeconomic differences in total caloric intake in the context of extreme differences in income distribution. Further examination showed that socioeconomic differences in total caloric intake appeared after controlling for alcohol intake. A complete analysis of the data suggests that lower income leads to lower cultural consonance, which in turn leads to higher depression, higher alcohol intake, and higher total caloric intake. In this model, alcohol ingestion can be seen as both a psychological and nutritional adaptive strategy to economic, social and cultural marginality in a highly stratified society.

Prenatal predictors of intimate partner abuse.

OBJECTIVE: To determine the prevalence of physical abuse and to identify predictors of abuse in a sample of pregnant women in Alabama. DESIGN: A prospective, correlational design was used. SETTING: Participants were drawn from four unrelated public and private prenatal clinics in Tuscaloosa, Alabama. PARTICIPANTS: The sample consisted of pregnant women between 20 and 34 years of age who had no high-risk health conditions and who initiated prenatal care during the 1st trimester. Four hundred thirty-nine ethnically diverse women completed interviews during the 1st and 3rd trimesters and had available birth outcomes. MAIN OUTCOME MEASURE: Physical abuse during pregnancy was measured by a modified version of the Abuse Assessment Screen. Bivariate and multiple logistic regressions yielded significant associations between individual predictors and physical abuse during pregnancy. RESULTS: The findings showed that 10.9% of the sample experienced physical abuse during the current pregnancy and 62% reported the intimate partner or former intimate partner to be the perpetrator. The best predictive model included stressful life events, depression, lack of faith in God or a higher power, and lack of contraceptive use.

Cultural consonance and adult body composition in urban Brazil.

In previous research in Brazil, we found socioeconomic and gender differences in body mass and percent body fat, consistent with a model in which individuals in higher socioeconomic strata, especially women, could achieve a cultural ideal of body size and shape. In this article, using new data, we examine these processes more precisely using measures of cultural consonance. Cultural consonance refers to the degree to which individuals approximate, in their own beliefs and behaviors, the shared prototypes for belief and behavior encoded in cultural models. We have found higher cultural consonance in several domains to be associated with health outcomes. Furthermore, there tends to be a general consistency in cultural consonance across domains. Here we suggest that measures of body composition can be considered indicators of individuals' success in achieving cultural ideals of the body, and that cultural consonance in several domains will be associated with body composition. Using waist circumference as an outcome, smaller waist size was associated with higher cultural consonance in lifestyle (beta = -0.311, P < 0.01) and higher cultural consonance in the consumption of high prestige foods (beta = -0.260, P < 0.01) for women (n = 161), but not for men (n = 106), controlling for age, family income, tobacco use, and dietary intake of protein and carbohydrates. Similar results were obtained using the body mass index and weight as outcomes, while there were no associations with height. These results help to illuminate the cultural mediation of body composition.

Social status and food preference in southern Brazil.

The prestige value of food and food behaviors is a topic of inquiry that complements the study of nutritional aspects of food use. In this work, varying social groups in Brazil are examined with regard to their evaluation of the status of available foods, and in turn, the frequencies with which they consume high and low status foods. Ethnographic and structured interviews were used to collect data, with agreement among groups tested by using Cultural Consensus Modeling. It was found that most social groups had a distinct notion of what foods are prestigious, although the high consumption of these same foods did not necessarily follow.
