The influence of gender and self-efficacy on healthy eating in a low-income urban population affected by structural changes to the food environment.

Although U.S. obesity prevention efforts have begun to implement a variety of system and environmental change strategies to address the underlying socioecological barriers to healthy eating, factors which can impede or facilitate community acceptance of such interventions are often poorly understood. This is due, in part, to the paucity of subpopulation health data that are available to help guide local planning and decision-making. We contribute to this gap in practice by examining area-specific health data for a population targeted by federally funded nutrition interventions in Los Angeles County. Using data from a local health assessment that collected information on sociodemographics, self-reported health behaviors, and objectively measured height, weight, and blood pressure for a subset of low-income adults (n = 720), we compared health risks and predictors of healthy eating across at-risk groups using multivariable modeling analyses. Our main findings indicate being a woman and having high self-efficacy in reading Nutrition Facts labels were strong predictors of healthy eating (P < 0.05). These findings suggest that intervening with women may help increase the reach of these nutrition interventions, and that improving self-efficacy in healthy eating through public education and/or by other means can help prime at-risk groups to accept and take advantage of these food environment changes.

Knowledge, attitudes, and beliefs about seasonal influenza and H1N1 vaccinations in a low-income, public health clinic population.

OBJECTIVE: The Public Health Center Vaccine Survey (PHCVS) examines the knowledge, attitudes, and beliefs about seasonal influenza and H1N1 vaccinations in a largely low-income, urban, public health clinic population in Los Angeles County, USA. DESIGN: A cross-sectional survey of vulnerable individuals at risk for severe influenza infection was conducted in one of the nation's largest local public health jurisdictions. SUBJECTS: A total of 1541 clinic patients were recruited in the waiting rooms of five large public health centers in Los Angeles County from June to August, 2010. RESULTS: Among prospective respondents who met eligibility criteria, 92% completed the survey. The majority was black or Latino and most were between the ages of 18 and 44 years. More than half were unemployed; two-thirds had no health insurance; and nearly one-half reported having a high school education or less. About one-fifth reported they had received the H1N1 vaccine during the previous flu season. In comparative analyses, negative beliefs about vaccine safety and efficacy were highly predictive of H1N1 vaccination. Blacks were less likely than non-black respondents to report receiving the H1N1 vaccine (OR=0.7, 95% CI=0.6-1.0). Blacks were also less likely than other respondents to agree that vaccines can prevent disease (OR=0.4, 95% CI=0.3-0.5), that vaccines are safe (OR=0.5, 95% CI=0.4-0.6), and that they trust doctors/clinicians who recommend vaccines (OR=0.5, 95% CI=0.4-0.7). CONCLUSIONS: Study findings provide a useful risk profile of vulnerable groups in Los Angeles County, which may be generalizable to other urban jurisdictions in the United States. They also describe real world situations that can be used to forecast potential challenges that vaccine beliefs may pose to national as well as local influenza pandemic planning and response, especially for communities with limited access to these preventive services.

The association between type of confidant and depressive symptomology in a sample of Mexican youth / Jóvenes mexicanos y depresión: el rol de confidentes

Background The current lifetime prevalence of depression among females in Mexico is 9.1% and 2.9% among males. The overall lifetime prevalence of depression is 6.2% among the general population of Mexico. Individuals that experience depressive symptomology at a young age are more likely to experience a depressive episode later in life. The risk of recurrence 24 months after the first episode of depression is 37.3%. There is scarce information about the prevalence of depression among adolescents in Mexico. However, a study of adults in Mexico City by Benjet et al. found that 2.8% of females and 1.1% of males experienced a depressive episode during adolescence. Research indicates that adolescents are especially vulnerable to mental and physical health problems. During the developmental transition, females are more vulnerable to these problems than males, including depression. The ways in which adolescents adapt and become adults can either protect or put them at risk for depressive symptomology and subsequent mental and physical disorders. The act of disclosure (talking to a confidant), which involves the sharing of personal thoughts and ideas with others, is an important mechanism through which adults and children form intimate relationships and develop good mental health. Objectives The objective of this study was to determine the association between type of confidant and depressive symptomology, and to identify some potential risk and protective factors of depression, including differences by gender, among a sample of Mexican youth. We hypothesized that not having a confidant would be associated with greater levels of depressive symptomology, and that this would differ by gender. Methods We used cross-sectional data obtained from 1,079 youths and adolescents aged 11 to 20 who were recruited to participate in the Health Worker Cohort Study (HWCS) between the years of 2004 and 2006. The HWCS included children and relatives of workers from the Instituto Mexicano del Seguro Social (IMSS) in Morelos and from Instituto Nacional de Salud Pública, both located in Cuernavaca. Participants were also selected from a similar sample of workers from the Universidad Autónoma del Estado de México (UAEM) in Toluca, capital of the State of Mexico. The participants from all three study sites are being followed in an ongoing cohort study of lifestyle and health. A self-reported questionnaire was administered to obtain information on lifestyle factors, socio-demographic data, health status, and quality of life. Bivariate and multivariate analyses were conducted to determine the association between confidant type and levels of depressive symptomology while controlling for demographic factors. Stratified analyses were also carried out, as it was hypothesized that the effect of disclosure to a confidant would vary by gender. Results In our study population, males had significantly lower levels of depressive symptomology than females; the mean BDI score for males was 5.6 and for females it was 8.7. Among both males and females, having only peer confidants is associated with higher levels of depressive symptomology, and having family confidants is associated with lower levels of depression. Males with peer confidants have the highest levels of depressive symptomology followed by those with no confidants, and those with family and peer confidants, as compared to males who reported having only a family confidant. Females with no confidant or with only peer confidants have higher levels of depressive symptomology than females with only family confidants. Among females, depressive symptomology increases with age, with females aged 17-20 having the highest levels of depressive symptomology. Financial symptomology predicts depressive symptomology among both males and females. Conclusions Our study shows that having a family member to talk to may be a protective factor against depressive symptomology among this sample of Mexican youth. Adolescents with a family confidant were found to have significantly lower levels of depressive symptomology than those who have only peer or no confidants. In the transition to adulthood, the presence of a family confidant positively influences the emotional well-being of boys and girls. Interventions that address the different disclosure needs of male and female adolescents may help reduce or prevent depressive symptomology among this population.

Antecedentes La prevalencia actual de depresión en México es de 9.1% en las mujeres y de 2.9% entre los hombres. En conjunto, la prevalencia de depresión entre la población general de México es de 6.2% durante el transcurso de la vida. Diversos estudios señalan que los individuos que presentan a edades tempranas un trastorno depresivo es más probable que más tarde en su vida sufran un episodio depresivo. El riesgo de presentar una recurrencia de depresión 24 meses después del primer episodio es de 37.3%. En México hay escasa información sobre la prevalencia de depresión entre los adolescentes. Las investigaciones señalan que los adolescentes son vulnerables a padecer problemas de salud tanto físicos como mentales. Durante la transición del desarrollo de la adolescencia, las mujeres son más vulnerables que los hombres a padecer este tipo de problemas, entre los que se encuentra la depresión. Las formas en que los adolescentes se adaptan y se convierten en adultos pueden protegerlos o ponerlos en riesgo de presentar trastornos depresivos y subsecuentes trastornos físicos y mentales. El acto de divulgar (platicar con un confidente) implica compartir pensamientos e ideas personales con otros y es un importante mecanismo por medio del cual los adultos y los niños forman relaciones cercanas y desarrollan una buena salud mental. Objetivos El objetivo de este estudio fue determinar la asociación entre el tipo de confidente y el trastorno depresivo e identificar algunos riesgos potenciales y factores protectores de depresión en una muestra de jóvenes mexicanos. Planteamos la hipótesis de que no contar con un confidente podría estar asociado con niveles más altos de sintomatología depresiva, asociación que podría ser distinta de acuerdo con el sexo. Métodos Se utilizaron los datos transversales recabados en 1079 jóvenes y adolescentes de 11 a 20 años, quienes fueron reclutados para participar en el Estudio Cohorte de Trabajadores (ECT) entre los años de 2004 a 2006. El ECT incluye niños y familiares de trabajadores del Instituto Mexicano del Seguro Social (IMSS) en Morelos y del Instituto Nacional de Salud Pública, ambos localizados en la ciudad de Cuernavaca. También se seleccionó una muestra similar de participantes de los trabajadores de la Universidad Autónoma del Estado de México (UAEM) en Toluca, capital del Estado de México. Los participantes de las tres sedes están en seguimiento en el estudio de cohorte prospectivo sobre salud y estilos de vida. Se administró un cuestionario autoaplicado para obtener información sobre datos sociodemográficos, estilos de vida, estado de salud y calidad de vida. Se realizaron análisis bivariados y multivariados para determinar la asociación entre el tipo de confidente y niveles de sintomatología depresiva controlando por factores sociodemográficos. Adicionalmente, se realizaron análisis estratificados bajo la hipótesis de que el efecto de divulgación a un confidente (platicar con un confidente) podría variar por sexo. Resultados En nuestra población de estudio, los hombres reportaron niveles significativamente más bajos de trastorno depresivo que las mujeres; la media de la puntuación del Inventario de Depresión de Beck (BDI) fue de 5.6 para hombres y de 8.7 para las mujeres. Entre ambos, tanto hombres como mujeres, contar sólo con amigos como confidentes se asocia con altos niveles de trastorno depresivo y contar con familiares como confidentes se asocia con menores niveles de depresión. Los hombres que cuentan con amigos como sus confidentes tienen los niveles más altos de sintomatología depresiva, seguidos por aquellos que cuentan con confidentes y de quienes cuentan como confidentes a amigos y familiares. Las mujeres que no tienen confidentes o que sólo cuentan con amigos como confidentes tienen niveles más altos de sintomatología depresiva que las que sólo cuentan con familiares como confidentes. Entre las mujeres, la sintomatología depresiva se incrementa con la edad; como lo señalan nuestros resultados las mujeres de 17 a 20 años presentaron los niveles más altos de sintomatología depresiva. En relación con otros factores asociados, encontramos que, tanto en hombres como en mujeres, el estrés financiero es un predictor de sintomatología depresiva. Conclusiones Nuestro estudio señala que contar con un miembro de la familia con quien platicar es un factor protector contra el trastorno depresivo en esta muestra de jóvenes mexicanos. Los adolescentes que cuentan con un familiar como confidente presentan niveles de sintomatología depresiva significativamente menores que aquellos que sólo cuentan con amigos o quienes no tienen confidentes. En la transición hacia la adultez, la presencia de un familiar como confidente influye positivamente en el bienestar emocional de niñas y niños. Las intervenciones que toman en cuenta las diferentes necesidades de divulgación de los adolescentes (de contar con un confidente) podrían ayudar a reducir o prevenir la sintomatología depresiva en esta población.
