Parental Feeding Styles and Their Association With Complementary Feeding Practices and Growth in Mexican Children.

Background: Complementary feeding practices and corresponding parental feeding styles influence nutritional status in later stages of childhood. Findings on the association of these variables with infant growth remain inconsistent; in Mexico, a research gap exists in this area. Research Aims: (1) To characterize parental feeding styles and complementary feeding practices, and (2) to evaluate the association of parental feeding styles with complementary feeding practices and infant growth at 6 and 9 months of age. Methods: Data were collected from a prospective Mexican birth cohort. Parental feeding styles, complementary feeding practices, and anthropometric data from 263 to 234 mother-child pairs (infants of 6 and 9 months of age, respectively) were analyzed. Logistic and linear regression models were used to determine the associations between variables. Results: The predominant parental feeding style was the "responsive style" (90%). Only 43.7 and 8.1% of 6- and 9-month-old infants, had adequate complementary feeding practices, respectively. At 6 months, mothers who were responsive to satiety signals had 11% lesser possibilities (OR = 0.89, 95% CI [0.80, 0.98]) of their infant having inadequate complementary feeding practices than their counterparts and "pressuring to finish" and "pressuring to eat cereal" sub-constructs were associated with lower weight for length and body mass index Z-scores (p = 0.02). Conclusions: A high proportion of infants (>40%) did not meet international recommendations. The "pressuring" parental feeding style sub-constructs were associated with growth indicators in 6-month old infants. This emphasizes the importance of promoting parental responsiveness to infant appetite and satiety signals to achieving adequate complementary feeding practices.

[Violence and mental health issues among Mexican adolescents that have considered or attempted cross-border migration]. / Violencia y salud mental asociados a pensar o haber intentado emigrar internacionalmente por adolescentes mexicanos.

The aim of this study was to estimate the role of victimization by violence among Mexican adolescents that have considered or attempted migrating to the United States, including mental health variables (emotional self-esteem, self-esteem in school, depression, suicidal ideation, and attempted suicide) as mediators of the effects. The study used a cross-sectional design with a stratified cluster sample of 13,198 adolescents from the 2nd Mexican National Survey on Exclusion, Intolerance, and Violence in public schools in 2009. The analysis used the regression models proposed by Baron & Kenny. Prevalence of having considered or attempted cross-border migration was 23.1%. Mean age was 16.36 years. Female adolescents constituted 54.9% of the sample, and 56% were lower-income. Mental health variables that acted as partial mediators were suicidal ideation (35.9%), depression (19.2%), attempted suicide (17.7%), emotional self-esteem (6.2%), and self-esteem in school (3.4%) for moderate family violence, and emotional self-esteem (17.5%) for social rejection in school and suicidal ideation (8.1%) for physical harm in school. Female adolescents showed greater impact from mediators than men in considering or having attempted cross-border migration. The study discusses the importance of incorporating the prevention of violence in the social contexts studied here and incorporating mental health in dealing with violence in adolescents and in public health programs in transit areas for illegal migrants.

Development and Validation of an Instrument to Evaluate Perceived Wellbeing Associated with the Ingestion of Water: The Water Ingestion-Related Wellbeing Instrument (WIRWI).

BACKGROUND: Ingestion of water has been associated with general wellbeing. When water intake is insufficient, symptoms such as thirst, fatigue and impaired memory result. Currently there are no instruments to assess water consumption associated with wellbeing. The objective of our study was to develop and validate such an instrument in urban, low socioeconomic, adult Mexican population. METHODS: To construct the Water Ingestion-Related Wellbeing Instrument (WIRWI), a qualitative study in which wellbeing related to everyday practices and experiences in water consumption were investigated. To validate the WIRWI a formal, five-process procedure was used. Face and content validation were addressed, consistency was assessed by exploratory and confirmatory psychometric factor analyses, repeatability, reproducibility and concurrent validity were assessed by conducting correlation tests with other measures of wellbeing such as a quality of life instrument, the SF-36, and objective parameters such as urine osmolality, 24-hour urine total volume and others. RESULTS: The final WIRWI is composed of 17 items assessing physical and mental dimensions. Items were selected based on their content and face validity. Exploratory and confirmatory factor analyses yielded Cronbach's alpha of 0.87 and 0.86, respectively. The final confirmatory factor analysis demonstrated that the model estimates were satisfactory for the constructs. Statistically significant correlations with the SF-36, total liquid consumption and simple water consumption were observed. CONCLUSION: The resulting WIRWI is a reliable tool for assessing wellbeing associated with consumption of plain water in Mexican adults and could be useful for similar groups.

[Gender role orientation and tobacco and alcohol use among youth in Morelos, Mexico]. / Orientación al rol de género y uso de tabaco y alcohol en jóvenes de Morelos, México.

OBJECTIVE: To quantify the association between gender role orientation and tobacco and alcohol use among young people of the State of Morelos. MATERIALS AND METHODS: Study conducted in 2004-2005, students aged 14 to 24 years (n = 1 730). Sociodemographic variables (area of residence, socioeconomic status), family (parental education and violence), psycho-sociological (gender role, self-esteem, depression, alcohol consumption, tobacco, locus of control, sexual abuse). Logistic regression analysis. RESULTS: Factors associated with use of tobacco: In women, being androgynous undesirable, masculine role, attempted sexual abuse and urban areas. For men, depression and submission. Factors associated with alcohol use: In women, masculine gender role; and in men to be older than 20 years, living in semi-urban and urban area, and internal locus. CONCLUSIONS: The machismo is one of the gender role orientations with greater association with the use of tobacco primarily in girls in Mexico, and the masculine or instrumental role with alcohol.

OBJETIVO: Cuantificar la asociación entre orientación al rol de género y uso de tabaco y alcohol en jóvenes del estado de Morelos. MATERIAL Y MÉTODOS: Estudio transversal realizado en 2004-2005, en jóvenes de 14 a 24 años (n=1 730). Variables sociodemográficas (zona de residencia, nivel socioeconómico); familiares (educación y violencia paternal); psicosociológicas (rol de género, autoestima, depresión, consumo de alcohol, tabaco, locus de control, abuso sexual). Análisis por regresión logística. RESULTADOS: Factores asociados con uso de tabaco: en mujeres, andrógina, no deseable, machista, intento de abuso sexual y zona urbana. Para hombres, depresión y sumisión. Factores asociados con uso de alcohol: en mujeres, rol masculino, y hombres, edad más de 20 años, vivir en zona semiurbana y urbana y locus interno. CONCLUSIONES: El machismo es una de las orientaciones al rol de género con mayor asociación con el uso de tabaco principalmente en las jóvenes, y la orientación masculina o instrumental se asocia con el alcohol.
