A Longitudinal Study of Cultural Consonance, Personal Agency, and Psychological Distress in Urban Brazil.

The relationship between culture, as a set of norms that structure human social practice, and agency, as the human capacity to act, has been debated for decades. Achieving clarity in how these constructs intersect has been hampered by difficulty in measuring either one, and theory has not suggested how a model linking culture and agency might be specified. We present a model in which culture is measured as cultural consonance, or the degree to which individuals actually incorporate prototypes for behavior encoded in cultural models into their own behavior.

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.

Statins Prescriptions and Lipid Levels in a Tertiary Public Hospital.

Background: The development of a new class of medications that are highly capable of reducing LDL-cholesterol renewed the interest in the characterization of familial hypercholesterolemia patients. Nevertheless, little is known about the lipid profile of patients in tertiary healthcare centers in Brazil in order to better estimate the real occurrence of familial hypercholesterolemia, with initial suspect of LDL-cholesterol levels above 190 mg/d/L.

Objectives: This study evaluated the lipid profile (total cholesterol and LDL-cholesterol) in ambulatory patients from a general tertiary public hospital.

Culture as a mediator of gene-environment interaction: Cultural consonance, childhood adversity, a 2A serotonin receptor polymorphism, and depression in urban Brazil.

Research on gene-environment interaction was facilitated by breakthroughs in molecular biology in the late 20th century, especially in the study of mental health. There is a reliable interaction between candidate genes for depression and childhood adversity in relation to mental health outcomes. The aim of this paper is to explore the role of culture in this process in an urban community in Brazil.

The interaction of cultural consonance and a polymorphism in the 2A serotonin receptor in relation to depression in Brazil: failure to replicate previous findings.

Objectives: To replicate a previously identified gene-environment interaction between a genetic polymorphism in the serotonin 2A receptor and cultural consonance in family life in relation to depressive symptoms (Dressler et al., 2009).

Methods: A sample of 402 individuals in a sample drawn from four different economic strata in Ribeirão Preto, Brazil was interviewed and genotyped.

UCP1 -3826 A>G polymorphism affects weight, fat mass, and risk of type 2 diabetes mellitus in grade III obese patients.

Objective: We investigated whether or not the UCP1 -3826 A>G polymorphism is associated with obesity and related metabolic disorders in grade III obese patients.

Methods: 150 obese patients (body mass index ≥35 kg/m(2)) who were candidates for bariatric surgery were studied. Weight (kg), body mass index (kg/m(2)); fat free mass (kg), fat mass (kg), energy intake (kcal), level of physical activity, plasma levels of glucose, total cholesterol, low-density lipoprotein, high-density lipoprotein (HDL), triacylglycerols, and the prevalence of comorbidities associated with obesity were collected from medical records.

Eating Disorders: Cultural Model and Consensus Regarding Food.

The cultural model of food was applied to 112 adult patients with eating disorders (PG) and 36 healthy adult women (CG) of similar age. The Free List and Ranking of Foods was used to group foods and verify consensus and cultural aspects. Calories, health, and taste were the dimensions used by the participants to group the foods, and strong consensus was achieved in regard to calories and health.

Culture and the Immune System: Cultural Consonance in Social Support and C-reactive Protein in Urban Brazil.

In this article, we examine the distribution of a marker of immune system stimulation-C-reactive protein-in urban Brazil. Social relationships are associated with immunostimulation, and we argue that cultural dimensions of social support, assessed by cultural consonance, are important in this process. Cultural consonance is the degree to which individuals, in their own beliefs and behaviors, approximate shared cultural models.

Bioelectrical impedance vector analysis in obese women before and after bariatric surgery: changes in body composition.

Objective: Because of the inefficacy of standard methods for the evaluation of body composition of grade III obese individuals, it is difficult to analyze the quality of weight loss after bariatric surgery in these patients. Electrical bioimpedance vector analysis and the RXc graph uses crude resistance (R) and reactance (Xc) values, like components of the Z vector, to monitor variations in body fluid and the nutritional status of obese individuals. Using bioelectrical impedance vector analysis (BIVA) and the RXc graph, the objective of the present study was to evaluate long-term changes in weight and body composition of obese women after Roux-en-Y bariatric surgery.

Protein and amino acid status before and after bariatric surgery: a 12-month follow-up study.

Background: Patients with obesity submitted to bariatric surgery present altered ingestion of macronutrient and micronutrient levels and nutrients deficiency. The objective of this study was to evaluate the protein and amino acid nutritional status of obese adults before and after bariatric surgery, with emphasis on plasma free amino acids.

Methods: Thirty obese women were submitted to Roux-en-Y gastric shunt (bariatric surgery).

Iron (FeSo4) bioavailability in obese subjects submitted to bariatric surgery.

Background: Iron bioavailability in obese subjects after the ingestion of a nutritional supplement was the aim of this work.

Methods: Fourteen persons were studied before and after bariatric surgery after the ingestion of a nutritional formulation containing 25 mg iron, 25 g fiber and 800 mg calcium.

Results: The following ferremia values (median and minimum--maximum) were obtained before and after bariatric surgery, respectively: Fasting, 105 (70 - 364) μg/dL and 198 (38 - 617) μg/dL; 1 hour, 103 (63 - 305) μg/dL and 160 (11 - 207) μg/dL; 2 hours, 103 (62 - 150) μg/dL and 141 (10 - 412) μg/dL; 3 hours.

Bioavailability of iron measurement in two nutrients multiple solutions by in vitro and in vivo;a comparative methodology between methods.

Objectives: The bioavailability of dietary iron present in a nutritional formulation may be evaluated by in vitro and in vivo methods since they provide for a cohesive line study and provided in the literature. The aim of this study was to evaluate the bioavailability of iron targeting a comparative analysis of two nutritional supplement formulations (A and B).

Methods: For this study were using in vitro and in vivo methods, both described in the literature for availability of iron in an enteral feeding after ingestion supplement nutrition with much nutrients.

The I405V and Taq1B polymorphisms of the CETP gene differentially affect sub-clinical carotid atherosclerosis.

Background: Cholesteryl ester transfer protein (CETP) plays a major role in lipid metabolism, but studies on the association of CETP polymorphisms with risks of cardiovascular disease are inconsistent. This study investigated whether the CETP gene I405V and Taq1B polymorphisms modified subclinical atherosclerosis in an asymptomatic Brazilian population sample.

Methods: The polymorphisms were analyzed using polymerase chain reaction in 207 adult volunteers.

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.

Daily vitamin supplementation and hypovitaminosis after obesity surgery.

Objective: The objective of this study was to determine whether constant daily vitamin supplementation would be sufficient to prevent possible vitamin deficiencies in obese patients undergoing bariatric surgery.

Methods: The study was conducted on 58 men and women (mean age 41 ± 10 y) who underwent Roux-en-Y gastric bypass RYGB and were assessed preoperatively and at 3, 6, and 12 mo after surgery. During the postoperative period, the patients received a multivitamin-mineral supplement on a daily basis.

Does perceived stress mediate the effect of cultural consonance on depression?

The importance of appraisal in the stress process is unquestioned. Experience in the social environment that impacts outcomes such as depression are thought to have these effects because they are appraised as a threat to the individual and overwhelm the individual's capacity to cope. In terms of the nature of social experience that is associated with depression, several recent studies have examined the impact of cultural consonance.

Change in predicted 10-year cardiovascular risk following Roux-en-Y gastric bypass surgery: who benefits?

Background: The risk of developing cardiovascular disease is higher in obese than in non-obese individuals. Surgery for obesity is effective in reducing weight and resolution of diabetes, hypertension, and dyslipidemia. Our aim was to assess the estimated 10-year cardiovascular risk of obese patients before and after treatment of obesity with a gastric bypass.

An evaluation of the genotoxic and cytotoxic effects of the anti-obesity drugs sibutramine and fenproporex.

Anti-obesity medications deserve special considerations at the present time due to an increasing number of overweight and obese people who require these therapeutic alternatives. Obesity is positively associated with several chronic illnesses, including cancer. In this work, we evaluated the possible genotoxic and/or cytotoxic actions of two drugs, sibutramine and fenproporex, in the doses of 10, 20 and 40 mg/kg body weight (bw), administered intraperitoneally in male Swiss mice.

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.

Nutritional course of patients submitted to bariatric surgery.

Background: Surgical treatment has proved to be effective for weight loss, improving the quality of life of obese individuals. However, metabolic and nutritional deficiencies may occur during the late postoperative period. The objective of the present study was to assess the metabolic and nutritional profile of grade III obese individuals for 12 months after Roux-en-Y gastric bypass (RYGBP).

Cultural consonance, a 5HT2A receptor polymorphism, and depressive symptoms: a longitudinal study of gene x culture interaction in urban Brazil.

In this study in urban Brazil we examine, as a predictor of depressive symptoms, the interaction between a single nucleotide polymorphism in the 2A receptor in the serotonin system (-1438G/A) and cultural consonance in family life, a measure of the degree to which an individual perceives her family as corresponding to a widely shared cultural model of the prototypical family. A community sample of 144 adults was followed over a 2-year-period. Cultural consonance in family life was assessed by linking individuals' perceptions of their own families with a shared cultural model of the family derived from cultural consensus analysis.
