Trends of Overweight and Obesity Among Children in Tijuana,Mexico

The objectives of this study were to compare the trends of obesity from 2001–02 to 2006–07 in school children of Tijuana, Mexico and to investigate the relationship with the child's gender and type of school attended. Bietapic random sample was selected by cluster of schools and groups. Results of the 1684 children from 6–14 years of age assessed showed an overall prevalence of obesity (> 95^th) of 28%. An overall increase of overweight and obesity of 7-percentage points (p = 0.0003), from 41 to 48%, being higher among boys and younger girls. Prevalence of obesity was higher among boys and children from private schools.     

Nutrition Knowledge and Food Choices of Elementary School Children

This research investigated the effect of a three-week school based nutrition education program on the nutrition knowledge and healthy food choices of 187 fifth graders who were randomly divided into a control ( n =97) or an experimental ( n =90) group. The control group received no nutrition education while the experimental group received 45 minutes of nutrition education, 4 days a week for 3 weeks. Nutrition knowledge scores and 3-day food records were collected at the beginning of the study and after 3 weeks. Food records were used to evaluate healthy food choices ( i.e. Dietary Guideline's recommended intake for macronutrients and the recommendations of the Food Guide Pyramid for each food group). In the experimental group there was a significantly greater increase in nutrition knowledge score ( p =0.001) and significant change in compliance in meeting the Dietary Guidelines ( p =0.0001) and the Food Guide Pyramid's recommendations ( p =0.0001). This study showed the effectiveness of a nutrition education program on nutrition knowledge scores and healthy food choices of fifth grade children.

Social Cognitive Model of Fruit and Vegetable Consumption in Elementary School Children

Fruit and vegetable consumption is related to reduced risk for certain forms of cancer. Health organizations recommend the increased consumption of fruit and vegetables. Despite these recommendations, few U.S. children eat the recommended number of at least five servings of fruit and vegetables per day. Understanding the determinants of consumption might improve our ability to increase consumption. Few theory-based models have been developed to explain and predict the consumption of various foods by children. This study proposed a model to explain fruit and vegetable consumption in children based on Social Cognitive Theory and on the literature in nutrition education. The model was tested using structural equation modeling techniques. Data from 414 third-graders were gathered on five predictors including availability, modeling, nutrition education, motivation (i.e., self-efficacy, outcome expectancies, food preferences), and knowledge. The proposed model was tested with two random splits of the data and also separately for males and females. Results indicate adequate fit of the models for each of the four data sets (split 1, split 2, males, females). The pattern of significant paths was similar across the data sets. Availability and motivation (i.e., self-efficacy, outcome expectancies, food preference) were most consistently related to consumption and to other constructs in the model.

Healthy and Unhealthy Food Consumption in Relation to Quality of Life among Finnish Female Municipal Employees: A Cross-Sectional Study

Aspects of good quality of life (QoL) have been found to motivate people to make lifestyle changes. There is also evidence that certain dietary patterns are associated with QoL. The aim of this work was to examine whether consumption frequencies of healthy and unhealthy food items are associated with QoL in female employees. A cross-sectional study was conducted among 631 Finnish female employees (mean age 49 years, SD = 10) from 10 municipal work units in 2015. Information about the participants was collected by physical examination, laboratory tests, self-administered questionnaires, including the Food Frequency Questionnaire (FFQ), and from medical history. QoL was assessed with the EUROHIS-Quality of Life 8-item index. A significant positive association was seen between consumption frequency of healthy foods and the EUROHIS-QOL mean score (p = 0.002). The association was small but comprehensive, also involving most dimensions of QoL. The consumption frequency of unhealthy foods was not associated with QoL. These findings are relevant when designing diet counselling, since QoL is an outcome that has been found to motivate people to change their health habits. Recommending abundant use of healthy foods could be a simple and convenient way of diet counselling at many health care appointments, where time consuming approaches are difficult to conduct.     

Project FIT: A School,Community and Social Marketing Intervention Improves Healthy Eating Among Low-Income Elementary School Children

Project FIT was a two-year multi-component nutrition and physical activity intervention delivered in ethnically-diverse low-income elementary schools in Grand Rapids, MI. This paper reports effects on children’s nutrition outcomes and process evaluation of the school component. A quasi-experimental design was utilized. 3rd, 4th and 5th-grade students (Yr 1 baseline: N = 410; Yr 2 baseline: N = 405; age range: 7.5–12.6 years) were measured in the fall and spring over the two-year intervention. Ordinal logistic, mixed effect models and generalized estimating equations were fitted, and the robust standard errors were utilized. Primary outcomes favoring the intervention students were found regarding consumption of fruits, vegetables and whole grain bread during year 2. Process evaluation revealed that implementation of most intervention components increased during year 2. Project FIT resulted in small but beneficial effects on consumption of fruits, vegetables, and whole grain bread in ethnically diverse low-income elementary school children.

Community-based survey of maquiladora workers in Tijuana and Tecate, Mexico

Responses to a survey of 177 maquiladora workers by specially trained peers suggest that transnational corporations operating the plants are ignoring Mexican regulations regarding hazard communication, training, health and safety committees, and uncontrolled hazards in the workplace. The "global standard" for workplace health and safety, often claimed by transnationals, should be made a reality.     

Sex Work Regulation and Sexually Transmitted Infections in Tijuana,Mexico

While reducing the transmission of sexually transmitted infections is a common argument for regulating sex work, relatively little empirical evidence is available regarding the effectiveness of these policies. We investigate the effects of highly publicized sex work regulations introduced in 2005 in Tijuana, Mexico on the incidence of trichomoniasis. State‐level, annual data for the 1995–2012 period are employed that include the incidence rates of trichomoniasis by age group and predictor variables. We find that the regulations led to a decrease in the incidence rate of trichomoniasis. Specifically, while our estimates are somewhat noisy, the all‐ages incidence rate in the 2005–2012 period is roughly 37% lower than what is predicted by our synthetic control estimates and corresponds to approximately 800 fewer reported cases of trichomoniasis per year. We find that the decreases are especially pronounced for 15–24 and 25–44 age cohorts. Copyright © 2016 John Wiley & Sons, Ltd.     

A skin test survey of valley fever in Tijuana, Mexico

Results of a study of the prevalence of valley fever among 1128 residents of Tijuana, Baja California are presented. Children from primary and middle schools (n = 497) and adults from technical institutes and maquiladoras (assembly plants) were tested for reaction to both spherulin and coccidioidin during 1985-1986, and they completed a questionnaire containing 23 variables on their socio-environment. Place of residence was mapped. The population sampled is largely middle class. Discriminant analysis indicates the distribution of positive cases is not clustered, nor can it be correlated with geomorphic factors such as mesa tops, canyons, or valley bottoms.     

Association between Emotional Eating and Frequency of Unhealthy Food Consumption among Taiwanese Adolescents

Emotional eating is one factor that increases the consumption of unhealthy food. This study aimed to investigate the association between emotional eating and frequencies of consuming fast food, high-fat snacks, processed meat products, dessert foods, and sugar-sweetened beverages (SSBs) in adolescents. The baseline survey data (2015) from the Taiwan Adolescent to Adult Longitudinal Study (TAALS) were fitted into multivariate logistic regression models adjusted for sex, school type, Body Mass Index (BMI), eating while doing something, nutrition label reading, skipping breakfast, smoking, binge drinking, sedentary lifestyle, physical activity, peer and school support, and parental education level. Among the 18,461 participants (48.5% male and 51.5% female), those exhibiting emotional eating were more likely to consume fast food (Odds ratio (OR) = 2.40, 95% Confidence interval (CI): 2.18–2.64), high-fat snacks (OR = 2.30, 95% CI: 2.12–2.49), processed meat products (OR = 1.92, 95% CI: 1.78–2.08), dessert foods (OR = 2.49, 95% CI: 2.31–2.69), and sugar-sweetened beverages (OR = 1.83, 95% CI: 1.70–1.98). Factors that were positively associated with unhealthy food consumption included eating while doing other activities, binge drinking, smoking, and sedentary lifestyle. Among all the covariates, nutrition label reading was the only factor that was inversely associated with frequent unhealthy food consumption. Sex and school type may moderate the effect of emotional eating on the frequent consumption of specific unhealthy food groups. In conclusion, adolescents with high emotional eating were more likely to report frequent consumption of unhealthy foods in Taiwan. Our findings showed that male participants appeared to consume fast foods, high-fat snacks, processed meat, and SSBs more often and dessert foods less often than females. Future longitudinal studies are recommended for understanding the causal relationship between emotional eating and unhealthy food consumption.     

A Qualitative Exploration of Female Sex Work in Tijuana, Mexico

Previous research has documented high rates of STDs and increased risk of HIV infection among female sex workers (FSWs) in Mexico; however, little is known about the sexual risk behaviors of this population. The purpose of this study was to explore work history, context of sex work, sexual risk practices, client characteristics, attitudes toward condoms, and potential barriers to condom use in a sample of FSWs in Tijuana, Mexico. Analysis of qualitative data from 25 FSWs revealed that most women entered the sex trade at a young age ( M = 23 years), primarily as a result of financial need. Forty percent were single mothers supporting children. Women worked an average of 6-7 days per week; work shifts ranged from 4 to 13 hr per day. Clients were both Mexican and foreign (mostly American and Asian), and ranged in age from 18 to 80 years. Positive aspects of the job included flexible work hours and good income. Negative aspects of sex work included risks associated with physical assault, diseases, and unwanted pregnancies. Most clients did not want to use a condom and many offered additional money for unprotected sex. FSWs did not like to use condoms because they were perceived as uncomfortable. Most FSWs did not negotiate the use of condoms, had a low knowledge regarding the proper use of condoms, and were reticent to report their own unsafe sex practices. These results suggest the need to develop culturally appropriate safer sex interventions for FSWs in Mexican border cities.     

Deportation experiences of women who inject drugs in Tijuana, Mexico

Deportation from the United States for drug offenses is common, yet the consequences of deportation for women drug users are poorly documented. In 2008, in Tijuana, Mexico, we conducted an exploratory qualitative study of migration, deportation, and drug abuse by interviewing 12 Mexican injection-drug-using women reporting U.S. deportation. Women reported heavy drug use before and after deportation, but greater financial instability and physical danger following deportation than when in the United States. We identified an unmet need for health and social services among deported drug-using women, including HIV prevention, drug treatment, physical and mental health services, and vocational training. Binational coordination is needed to help deported women resettle in Mexico.
