Objetivo: analisar a influência das composições familiares na ocorrência da gravidez na adolescência. Método: estudo caso-controle, realizado com 74 gestantes adolescentes, grupo de casos, e 74 adultas jovens sem história pregressa de gravidez na adolescência, grupo controle, pareadas pela variável renda familiar. Os dados foram coletados por meio de entrevistas estruturadas realizadas no período de agosto a outubro de 2016 em Cuiabá, Mato Grosso, e em seguida analisados pelos métodos estatísticos descritivo e inferencial. Resultados: identificou-se associação entre a ocorrência do desfecho com pertencer a famílias não nucleares, não permanecer a mesma família durante a infância e adolescência, e a constituição de uma família própria no período da adolescência. Conclusão: verificou-se que adolescentes inseridas em famílias não nucleares estão mais expostas a fatores de risco para ocorrência da gravidez na adolescência, quando comparadas às jovens provenientes de famílias com ambos os pais.ABSTRACTObjective: to analyze the influence of family compositions in the occurrence of pregnancy in adolescence. Method: this is a case-control study performed with 74 pregnant adolescents, group of cases, and 74 young adults without background history of pregnancy during adolescence, group control, paired by family income. Data were collected through structured interviews conducted in the period from August to October 2016 in Cuiabá, Mato Grosso, and then analyzed by descriptive and inferential statistical methods. Results: we identified an association between the occurrence of the outcome and the belonging to non-nuclear families, as well as the non-belonging to the same family during childhood and adolescence, besides the constitution of an own family in the period of adolescence. Conclusion: checked that adolescents inserted in non-nuclear families are more exposed to risk factors for the occurrence of pregnancy in adolescence when compared to young people coming from families with both parents.RESUMENObjetivo: analizar la influencia de las composiciones familiares en la ocurrencia del embarazo adolescente.

Background and purpose: Stunting in children is a chronic nutritional concern that has short-term and long-term health effects. Several studies have shown inconsistent results related to the association between stunting and anemia and increased maternal weight during pregnancy. This study aims to determine anemia during pregnancy, increased body weight and weight gain during pregnancy based on body mass index (BMI) before pregnancy stunting with.Method: A case control study was carried out using the baseline data of an intervention studyconducted from April to September to prevent stunting in children aged 6-23 months in nine villages in Bangli District, Bali Province. Baseline data collection was conducted from December 2017–February 2018 by interviews with 330 mothers of the children and observation of their ANC records. The number of samples for the case control study was 156 children aged 6-23 months consisting of 78 cases and 78 controls (1:1). Cases were selected by systematic random sampling from 82 children with stunting and controls were selected in the same way from 248 children without stunting. Data analyzed were maternal age at pregnancy, education, employment, number of children, family income, height, hemoglobin level and maternal body weight during pregnancy. Multivariate analysis with logistic regression was conducted to determine the adjusted odds ratio (AOR) of each risk factor.Results: The increase in maternal weight during pregnancy which is not in accordance with maternal BMI before pregnancy and an increase in maternal weight of <10 or >12.5 kilograms are significantly associated with stunting with AOR=3.53 (95%CI: 1,55-8.07) and AOR=3.31 (95%CI: 1.24-8.85). Hemoglobin <11gr/dL during pregnancy was not found to be significantly associated with stunting (AOR=5.02; 95%CI: 0.80–31.71).Conclusion: The increase of maternal weight during pregnancy which is not suitable with BMI before pregnancy and an increase in maternal weight of <10 or >12.5 kilograms are risk factors for stunting in children aged 6-23 months. In addition to monitoring the increase of maternal weight during pregnancy, it is important to consider the mother's BMI before pregnancy in order to reduce the risk of stunting.

Objective: The prevalence of type 2 diabetes mellitus (T2DM) varies greatly in different regions and populations. This study aims to assess the heritability and environmental risk factors of T2DM among rural Chinese adults.Methods: Thousand five hundred thirty three participants from 499 extended families, which included 24 nuclear families, were recruited in the family-based study to assess the heritable risk of T2DM. Heritability of T2DM was estimated by the Falconer method. Using conditional logistic regression model, couple case-control study involving 127 couples were applied to assess the environmental risk factors of T2DM.Results: Compared with the Henan Rural Cohort, T2DM was significantly clustered in the nuclear families (OR: 8.389, 95% CI: 5.537–12.711, P &lt; 0.001) and heritability was 0.74. No association between the heredity of T2DM and sex was observed between the extended families and the Henan Rural Cohort. Besides, results from the couple case-control study showed that physical activity (OR: 0.482, 95% CI: 0.261–0.893, P = 0.020) and fat intake (OR: 3.036, 95% CI: 1.070–8.610, P = 0.037) was associated with T2DM, and the proportion of offspring engaged in medium and high physical activity was higher than that of mothers in mother-offspring pairs.Conclusion: People with a family history of T2DM may have a higher risk of developing T2DM, however, there was no difference in genetic risk between males and females. Adherence to active physical activity and low fat intake can reduce the risk of T2DM.

Background: Breast cancer is a serious public health problem and is the second most prevalent cancer type in the world. The purpose of this article is to evaluate the association between pesticide use and breast cancer in a region of intense agribusiness activity in the state of Mato Grosso, Brazil. Methods: A case-control study was conducted on women living in the city of Rondonópolis, in the south of Mato Grosso state. There were 85 cases of women with confirmed breast cancer and 266 controls who were randomly selected from primary health care users. Bivariate and stratified analyses were performed. Multiple logistic regression was then performed, keeping in the final model the factors with a significance level lower than or equal to 0.05 or considered important according to apriori biological criteria. Results: In the final model, living near cropland with pesticides (OR: 2.37; CI: 95% 1.78–3.16) and women aged over 50 years who experienced early menarche (OR: 2.08; CI: 95% 1.06–4.12) had a higher risk of developing breast cancer compared to control subjects. Conclusion: This study highlights the importance of exposure to pesticides as an environmental risk factor for the development of breast cancer among women.

SummaryIn a case-control study among the urban poor of Dhaka, Bangladesh, the association of maternal education and family income with severity of disease due to diarrhoea in children was examined. After adjusting for family income, 7 or more years of school education was associated with 54% reduced risk of severe disease as indicated by the presence of dehydration. Income in the uppermost quartile of this population, independently of maternal education, was associated with 41% reduced risk of severe disease compared to the lowest quartile. In the logistic regression model the effect of maternal education remained high after adjustment for several confounders. Based on the concept that socioeconomic variables operate through a set of proximate variables it is contended that maternal education, independently of economic power, through its impact on disease from acute diarrhoea, favourably influences child survival.

ABSTRACTObjective: to analyze the relationship between lifestyle and other variables on hypertension. Method: this is about a case-control study performed with 120 users of the health unit of the district of Porto São Mateus/ES, matched the offer for one hypertensive of three normotensive. The instrument used was the profile of individual lifestyle as well as issues related to socio-economic profile. The project was approved by the Ethics Committee in Research of Centro Universitário Norte do Espírito Santo, of the Universidade Federal do Espírito Santo (043/2010). Results: there was a greater chance of developing hypertension with advancing age. The lifestyle was not statistically significant with hypertension, despite a greater exposure among normotensives. This fact can be attributed to a greater concern and health care by hypertensive only after the confirmation of the diagnosis of hypertension. Conclusion: adopting a healthy lifestyle from infancy to occur in order to prevent hypertension and not only serve as a treatment. Descriptors: life style; hipertensyon; risk factores.RESUMOObjetivo: analisar a relação do estilo de vida e de outras variáveis sobre a hipertensão arterial. Métodos: trata-se de um estudo de caso-controle realizado com 120 usuários da unidade de saúde do bairro Porto de São Mateus – ES, pareados na proporção de 3 hipertensos para 1 normotenso. O instrumento utilizado foi o Perfil do Estilo de Vida Individual além de questões relacionadas ao perfil sócio econômico. O projeto obteve aprovação do Comitê de Ética em Pesquisa do Centro Universitário Norte do Espírito Santo, da Universidade Federal do Espírito Santo, conforme parecer 043/2010. Resultados: observou-se maiores chances de desenvolver a hipertensão com o avanço da idade. O estilo de vida não apresentou significância estatística com a hipertensão arterial, apesar de uma maior exposição entre os normotensos. Tal fato pode ser atribuído a uma maior preocupação e cuidado com a saúde por parte dos hipertensos somente a partir da confirmação do diagnóstico de hipertensão. Conclusão: a adoção de um estilo de vida saudável deve ocorrer desde a infância a fim de se prevenir a hipertensão e não servir apenas como tratamento.

AbstractObjectiveHeight-for-age shorter than 3th percentile or 2 sd below the median of the National Center for Health Statistics/WHO growth reference is known as stunting. The present study aimed to measure the association of several factors with stunting in a cohort born from 2009 to 2010 in Shiraz, Iran.Design/Setting/SubjectsNested case–control study conducted on pre-school children in 2016. Participants were 200 children suffering from stunting (case group) and 200 children with normal height (control group).ResultsResults of multivariable logistic regression analysis suggested a significant relationship (adjusted OR; 95 % CI) between stunting and mother’s occupation (employed v. housewife: 3·58; 1·73, 7·39) and chronic diseases (yes v. no: 2·93; 1·25, 6·88). In addition, significant associations were found between family income (<10 million v. >30 million Rials: 5·63; 2·46, 12·87), diary consumption (very little v. high: 5·93; 1·74, 20·18) and animal protein in diet (low v. very high: 2·42; 1·13, 5·19) and stunting among children. Also, chance of stunting was inversely associated with birth interval (<2 years v. first child: 3·13; 1·45, 6·76) and duration of exclusive breast-feeding (18–24 months v. formula only or breast-feeding for <18 months: 0·53; 0·30, 0·92).ConclusionsMothers being housewife, possibly due to having more time to take care of their children, childhood diseases and consumption of dairy foods are strong and modifiable factors which can positively affect Iranian children’s stature. Higher family income is another important factor in stunting but under less parental control.

The relationship between malnutrition and social support was first suggested in the mid-1990s. Despite its plausibility, no empirical studies aimed at obtaining evidence of this association could be located. The goal of the present study was to investigate such evidence. A case–control study was carried out including 101 malnourished children (weight-for-age National Center for Health Statistics/WHO 5th percentile) aged 12–23 months, who were compared with 200 well-nourished children with regard to exposure to a series of factors related to their social support system. Univariate and multiple logistic regressions were carried out, odds ratios being adjusted for per capita family income, mother's schooling, and number of children. The presence of an interaction between income and social support variables was also tested. Absence of a partner living with the mother increased risk of malnutrition (odds ratio 2·4 (95 % CI 1·19, 4·89)), even after adjustment for per capita family income, mother's schooling, and number of children. The lack of economic support during adverse situations accounted for a very high risk of malnutrition (odds ratio 10·1 (95 % CI 3·48, 29·13)) among low-income children, but had no effect on children of higher-income families. Results indicate that receiving economic support is an efficient risk modulator for malnutrition among low-income children. In addition, it was shown that the absence of a partner living with the mother is an important risk factor for malnutrition, with an effect independent from per capita family income, mother's schooling, and number of children.

Introducción. Se estima que, aproximadamente, 6,8 a 8,9 millones de personas están infectadas por el virus de la hepatitis C en Latinoamérica, de las cuales menos del 1 % llega a recibir tratamiento antiviral. En los estudios llevados a cabo hasta ahora en Colombia, se ha propuesto determinar la prevalencia de la enfermedad en algunos grupos de riesgo, y no se ha hecho el análisis de otros factores potencialmente implicados en el contagio.Objetivos. Determinar los factores de riesgo tradicionalmente analizados y otros no estudiados antes para la hepatitis C crónica en la Costa Caribe colombiana.Materiales y métodos. Se hizo un estudio de casos y controles (1:3) emparejados por empresa promotora de salud y edad (± 10 años), en el primer nivel de atención de hepatología y gastroenterología. A todos los pacientes positivos en la prueba ELISA se les hizo una prueba confirmatoria de carga viral. En el análisis de regresión logística multivariable se determinaron los factores predictores independientes de infección.Resultados. La transfusión sanguínea (odds ratio, OR=159,2; IC95% 35,4-715; p<0,001) y el antecedente de hospitalización antes de 1994 (OR=4,7; IC95% 1,3-17,1; p=0,018) se determinaron como los dos únicos factores independientes predictores de infección.Conclusión. Es necesario comprobar la reproducibilidad de estos resultados y hacer estudios de costo-efectividad antes de recomendar su utilización en el diseño de nuevas estrategias de cribado.
