Improving the transitional experience of previously incarcerated women a nutritional needs assessment at a transitional home in Houston, Texas

Transitional homes present a window of opportunity to address the nutrition-related chronic diseases of previously incarcerated women. However, few transitional facilities offer nutrition education programs. This study assesses the nutritional status of 9 previously incarcerated women living at a transitional home in Houston, Texas and makes recommendations for effective nutrition education programs. Data was collected through individual interviews, questionnaires and a 24-hour dietary recall. Participants differed significantly from national nutrition recommendations when comparing BMI values and fruit, vegetable and fiber intake. Qualitative interview themes concerned key barriers to healthful dietary intake such as inadequate food storage and inconvenient cooking environment. Nutrition education programs at transitional homes should focus on healthy meals and snacks that can be quickly prepared and easily stored in small spaces. ^

The effect of specific carotenoids on lung cancer risk

A population-based case-comparison study of histologically confirmed lung cancer among white male and female residents of six Texas coastal counties was conducted from 1979-1982. Dietary information as well as information concerning smoking, alcohol consumption, occupational and residential exposures, and family history of cancer was obtained from 149 living cases and 359 comparison subjects.^ These data support the findings of previous studies that reported a protective association of total carotene intake with lung cancer (OR = 4.07, CI = 3.36-4.78), and no association for total Vitamin A or retinol. Of six specific carotenoids examined, these data reveal a statistically significant protective effect for alpha carotene (OR = 3.58, CI = 2.85-4.31), and an elevated, although non-significant effect for beta carotene (OR = 1.46, CI = 0.61-2.31). No consistent significant effect was found for cryptoxanthin, other xanthins, lutein or lycopene.^ Similar results were found for both males and females, and for both squamous cell and adenocarcinoma subtypes, although loss of power resulting from stratification may have rendered the celltype specific results more imprecise. These results should be considered with caution until confirmed by other studies, however, they suggest the importance of evaluating specific carotenoids in future diet-lung cancer investigations. ^

THE RECOVERY OF ENTEROPATHOGENS FROM CONTAMINATED COOKED FOODS AT HOLDING TEMPERATURES

Hot foods served in foodservice establishments, institutions and homes, have always been regarded as safe, since cooking temperatures are more likely to kill the bacterial agents that may cause foodborne diseases. However, foods that are otherwise served hot have been epidemiologically incriminated for causing foodborne diseases. This situation arises due to the possible post-cooking food contamination. Post-cooking contamination of hot-held food is most threatening for it gives the contaminating agents the possibility of proliferation. On one hand, post-cooking contamination is least understood and on the other, hot-holding of food gives the consumer a false sense of freedom from foodborne diseases. In this study, the dynamics of food contamination before or after cooking and during hot-holding are discussed and a food contamination dynamics model is presented.^ The literature on foodborne cholera, cholera-like diarrhea, shigellosis and E. coli gastroenteritis together with the literature on the occurrence and growth of the causative enteropathogens; 01 V. cholerae, non-01 V. cholerae, S. sonnei, S. flexneri and E. coli were reviewed. The literature on the infective doses of these organisms were also cited.^ In the study, four cooked food types held hot at 40-60(DEGREES)C were deliberately contaminated with 01 V. cholerae, non-01 V. cholerae, S. sonnei, S. flexneri and E. coli, one at a time at each of the hot-holding temperatures. Tested food samples for the recovery of these enteropathogens were withdrawn at various time intervals of hot holding.^ The results showed bacterial recovery to decline with increasing temperature and with increasing hot-holding time within each holding temperature. All the bacterial types except V. cholerae were recovered even after holding the food at 60(DEGREES)C for one hour. V. cholerae was not recovered after hot-holding the food at 50-60(DEGREES)C at certain holding periods. After 48 hrs incubation, V. cholerae was recovered on TCBS agar plates that read negative after the initial 24 hrs of incubation. Effective hot-holding temperatures were determined for each of the food types contaminated by each of the bacterial types.^ Statistical analysis of the collected data showed temperature, bacterial type and their interaction to be significant in enteropathogen recovery. Food type and its interactions with temperature and bacterial type were found not significant. ^

A STUDY TO INVESTIGATE DIET DIVERSITY AS A NUTRITION ASSESSMENT INSTRUMENT

Nutrient intake and specific food item data from 24-hour dietary recalls were utilized to study the relationship between measures of diet diversity and dietary adequacy in a population of white females of child-bearing age and socioeconomic subgroups of that population. As the basis of the diet diversity measures, twelve food groups were constructed from the 24-hour recall data and the number of unique foods per food group counted and weighted according to specified weighting schemes. Utilizing these food groups, nine diet diversity indices were developed.^ Sensitivity/specificity analysis was used to determine the ability of varying levels of selected diet diversity indices to identify individuals above and below preselected intakes of different nutrients. The true prevalence proportions, sensitivity and specificity, false positive and false negative rates, and positive predictive values observed at the selected levels of diet diversity indices were investigated in relation to the objectives and resources of a variety of nutrition improvement programs. Diet diversity indices constructed from the total population data were evaluated as screening tools for respondent nutrient intakes in each of the socioeconomic subgroups as well.^ The results of the sensitivity/specificity analysis demonstrated that the false positive rate, the false negative rate, or both were too high at each diversity cut-off level to validate the widespread use of any of the diversity indices in the dietary assessment of the study population. Although diet diversity has been shown to be highly correlated with the intakes of a number of nutrients, the diet diversity indices constructed in this study did not adequately represent nutrient intakes in the diet as reported, in this study, intakes as reported in the 24-hour dietary recall. Specific cut-off levels of selected diversity indices might have limited application in some nutrition programs. The results were applicable to the sensitivity/specificity analyses in the socioeconomic subgroups as well as in the total population. ^

THE APPLICATION OF PATH ANALYSIS TO ASSESSMENT OF IRON NUTRITIONAL STATUS IN MAN

Path analysis has been applied to components of the iron metabolic system with the intent of suggesting an integrated procedure for better evaluating iron nutritional status at the community level. The primary variables of interest in this study were (1) iron stores, (2) total iron-binding capacity, (3) serum ferritin, (4) serum iron, (5) transferrin saturation, and (6) hemoglobin concentration. Correlation coefficients for relationships among these variables were obtained from published literature and postulated in a series of models using measures of those variables that are feasible to include in a community nutritional survey. Models were built upon known information about the metabolism of iron and were limited by what had been reported in the literature in terms of correlation coefficients or quantitative relationships. Data were pooled from various studies and correlations of the same bivariate relationships were averaged after z- transformations. Correlation matrices were then constructed by transforming the average values back into correlation coefficients. The results of path analysis in this study indicate that hemoglobin is not a good indicator of early iron deficiency. It does not account for variance in iron stores. On the other hand, 91% of the variance in iron stores is explained by serum ferritin and total iron-binding capacity. In addition, the magnitude of the path coefficient (.78) of the serum ferritin-iron stores relationship signifies that serum ferritin is the most important predictor of iron stores in the proposed model. Finally, drawing upon known relations among variables and the amount of variance explained in path models, it is suggested that the following blood measures should be made in assessing community iron deficiency: (1) serum ferritin, (2) total iron-binding capacity, (3) serum iron, (4) transferrin saturation, and (5) hemoglobin concentration. These measures (with acceptable ranges and cut-off points) could make possible the complete evaluation of all three stages of iron deficiency in those persons surveyed at the community level. ^

HEAD OF HOUSEHOLD STRUCTURE: ITS INFLUENCE ON THE DIETARY QUALITY OF U.S. HOUSEHOLDS, 1977-78 (UNITED STATES, NATIONWIDE FOOD CONSUMPTION SURVEY)

Using analysis of variance, household data collected in the Spring portion of the 1977-78 Nationwide Food Consumption Survey conducted by the United States Department of Agriculture were analyzed to examine the relationship between household characteristics and dietary quality of the household food supply. Results indicated that head of household structure was a statistically significant variable, with female headed households having higher dietary quality.^ Further analysis indicated that neither race, degree of urbanization, regional location, the education level of the female head, nor her employment status were significant variables in influencing dietary quality. The influence of head of household structure remained significant when these variables were controlled. However, income, household size, and family life cycle stage had statistically significant effects on dietary quality, and when individually controlled, the influence of head of household structure disappeared. ^

THE EFFECT OF CAFFEINE CONSUMPTION ON MORTALITY IN HYPERTENSIVE INDIVIDUALS

The effect of caffeine consumption on mortality was evaluated in a historical cohort study of 10064 hypertensive individuals participating in the Hypertension Detection and Follow-Up Program (HDFP) from 1973 to 1979. The study cohort was stratified into caffeine consumption groups (none, low, medium and high) based on their total level of caffeine intake from beverages (coffee and tea) and certain medications at the One-year follow-up home visit. Stratification was also made by sex, race, type of care and age. The total relative risks (RRs) when computed across strata for each caffeine consumer group (low, medium and high) were not significantly different when compared to the noncaffeine consumer group for all-cause or cause-specific mortality rates. The point estimates and 95 per cent confidence intervals for relative risks of all-cause mortality when compared to nonconsumers were as follows: Low = 0.82 (0.65-1.03), Medium: = 0.82 (0.62-1.82) and High = 0.90 (0.63-1.28). For all sex, race combinations there was an increase in the per cent of current smokers within each caffeine consumer group as the level of caffeine consumption increased. Cigarette smoking was an important confounder correlated with caffeine consumption and associated with mortality in this cohort. When confounding by cigarette smoking was adjusted for in the analysis, no association was found between the level of caffeine consumption and all-cause or cause-specific mortality. ^

THE EFFECT OF IRON SUPPLEMENT ON THE GROWTH OF RURAL INDONESIAN SCHOOL CHILDREN

The effect of oral iron supplementation on blood iron levels and physical growth in 119 Indonesian rural school children was assessed in the double-blind study. The children were classified into anemic and normal groups according to their initial hemoglobin and transferrin saturation levels and were randomly assigned to either iron or placebo treatment for twelve weeks. Biochemical, anthropometric and morbidity data were collected prior to and after the treatment period. Before treatment, anemic subjects were smaller and had higher morbidity than normal subjects. Treatment with 10 mg ferrous sulfate/kg/day for twelve weeks resulted in a significant improvement in blood iron biochemical status of the anemic subjects and in their growth velocity and morbidity. ^

Mexico: A new heavy weight in a global world

In the last three decades, obesity has been gaining recognition as a serious public health problem in Mexico. This epidemic developed insidiously in a country that was still focused on chronic under-nutrition in the population. During that same period, macro-economic reforms projected Mexico into the global economic arena. Foreign investments, trade in goods and services, and technological transfers were promoted through participation in numerous trade agreements between Mexico and other countries. The North American Trade Agreement (NAFTA), signed in 1994, promised an integrated market between the three North American countries: Canada, the United States, and Mexico. Although these trade policies were likely to have effects on the available food supply in Mexico, this association has not been elucidated. In this case study, we examine how these trade liberalization policies may have influenced the food supply in Mexico.^ Information on the trade of food commodities between the United States and Mexico and the nature of foreign investment in Mexico was compiled using public data available through American, Mexican, and other international published reports for 1986 through 2011. After the implementation of NAFTA, an increase in trade and investments was observed between Mexico and its two North American partners, but most of the trade increase occurred between the US and Mexico. Since the liberalization of trade policies between these counties, exports of fruit and vegetables into the U.S. from Mexico have increased, while exports of cereals, fats, vegetable oils, meat, dairy products and processed foods from the U.S. into Mexico have increased. During this same time period, there has been an increase in the foreign direct investment in the food industry in Mexico, as well as changes in the types and amounts of dietary energy available on a population level. Specifically, between 1990 to 2006, the dietary energy supply per person has increased 6.1% available animal protein has increased 35.8%, and available fat has increased 18.9%.^ Thus, this case study suggests that the recent changes in food-related industries through foreign direct investment and market liberalization may be likely contributors to the obesogenic food environment in Mexico. Although this initial case study provides interesting data, whether trade liberalization policies should be considered hazardous for health as a distal determinant of the obesity epidemic needs to be further examined using a more stringent study design or further follow up of the US Mexico trade data.^

Using intervention mapping to develop a community garden program at the women's home

This culminating experience was a practice based intervention conducted by an organization, utilizing an intervention mapping approach for the program planning. It took place summer 2010 through spring 2011 and included incorporating a community garden into the Gusto wellness program at The Women's Home. This organization offers long-term residential care, and therapeutic services. Literature relating to community gardens and nutrition behavior change was reviewed. Short-term objectives included: 1) Conducting a needs assessment using focus groups, 2) Designing gardening program components based on intervention mapping guidelines, 3) Constructing a garden bed at Midtown Community Garden for use of The Women's Home, 4) Planning and implementing gardening education, and 5) Assessing feasibility of the garden program. The target population included 24 residents living at the residential dormitory of The Women's Home at the time of this project. The major variables are intervention mapping constructs including: 1) Needs assessment, 2) Preparing matrices of change objectives, 3) Selecting theory-informed intervention methods and practical strategies, 4) Producing program components and materials, 5) Planning program adoption, implementation, and sustainability, and 6) Planning for evaluation. The specific focus was lack of access to fresh fruits and vegetables (FV) for this population. Focus group responses revealed interest in community garden participation. Matrices of change were developed for lack of FV access based on performance objectives for behavioral and environmental factors and related determinants and theory. Methods and strategies were developed to implement a community garden and encourage participation. Program components included initiating a garden club, networking activities, creating gardening curriculum, and participating at Midtown Community Garden. Adoption and implementation performance objectives were outlined, and many were carried out. Evaluation questions were designed and outcomes of the garden project were discussed. ^ Outcomes of the project included exposure of garden topics and activities for The Women's Home residents, focus group responses revealing an interest in gardening among this population, gardening program components designed based on intervention mapping steps, and a constructed garden bed that was used for planting vegetables and flowers through fall 2010. Limited resources and budget along with a lack of a residential coordinator at The Women's Home were the main limiting factors for this project. Future garden projects can be developed using the intervention mapping process.^

Colorectal cancer: An insight on dietary factors

Aim. To assess the relationships between dietary factors and colorectal cancer risk. ^ Methods. We looked at all the systematic reviews published in last ten years on the topic. ^ Results. For fruits-vegetables some studies1 were significant for heterogeneity and others2 were not. In study by Aune at al3 only fruits were significant, although all the studies had protective RR between 0.90 to 0.94. For folate only case-control group of studies, the study by Sanjoaquin et al4 was significant with p heterogeneity being 0.01 and all of them had protective effect with RR between 0.75 to 0.95, for dietary as well as total folate. For fiber study by Park et al5 p was insignificant at 0.14 an RR was 0.84. Vitamin B6 study by Larsson et al6 had significant p with RR 0.90. For dietary fat both Alexander7 and Liu8 concluded that there is insufficient evidence that dietary fat is an independent causative risk factor. Only one study by Norat et al9 out of three was able to achieve significant p heterogeneity for meat. All the studies reported RR between 1.14 to 1.35, clearly implicating meat as culprit for increasing the risk of colorectal cancer. ^ Conclusions. We would recommend the use of fruits and vegetables to be protective against colorectal cancer. Also meat consumption increases the risk of colorectal cancer.^ *Please refer to dissertation for references/footnotes.^

Ethnic differences in food availability at home among 3--5 year old preschoolers attending Head Start centers in 2008

Background. The childhood obesity epidemic has disproportionately impacted the lives of low-income, minority preschoolers and their families. Research shows that parents play a major role as "gatekeepers" who control what food is brought into the home and as role models for dietary practices. Currently, there is limited research regarding ethnic differences in families of low-income preschoolers. ^ Objective. The objective of this study was to look at ethnic differences in food availability at home among the low-income families of Hispanic and African American preschoolers attending Head Start centers in Harris County, Texas. ^ Design/Subjects. Descriptive data on food availability at home between Hispanic and African American families were used and analyzed for this study. Parents or primary caregivers (n = 718) of children enrolled at Head Start Centers in Houston, Texas completed the Healthy Home Survey. ^ Methods. In the Healthy Home Survey, participants were asked to answer open-ended questions regarding various types of foods currently available at home, such as fresh, canned or jarred, dried and frozen fruits; fresh, canned or jarred, and frozen vegetables; salty snacks, sweet snacks, candy, and soda. Descriptive analyses were conducted to identify significant differences between Hispanics and African Americans via a paired t-test to compare the means of variables between the study groups and a Pearson's chi-square or Fischer's exact (if cell size was <5) test calculated for food availability (food types) between ethnicities to determine differences in distributions. ^ Results. Although both Hispanics and African Americans reported having all categories of food types at home, there were statistically significant differences between ethnic groups. Hispanics were more likely to have fresh fruits and vegetables at home than African Americans. At the same time, more African American families reported having canned or jarred fruits and canned green/leafy vegetables than Hispanics. More Hispanic families reported having diet, regular, and both diet and regular sodas available compared to African American families. However, high percentages of unhealthy foods (including snacks and candy) were reported by both ethnicities. ^ Conclusions. The findings presented in this study indicate the implicit ethnic differences that exist in the food availability among low-income families of Hispanic and African American preschoolers. Future research should investigate the associations between food availability and children's weight status by ethnicity to identify additional differences that may exist.^

Infant breastfeeding patterns by sex: Do males feed more?

Background: Most studies have looked at breastfeeding practices from the point of view of the maternal behavior only, however in counseling women who choose to breastfeed it is important to be aware of general infant feeding patterns in order to adequately provide information about what to expect. Available literature on the differences in infant breastfeeding behavior by sex is minimal and therefore requires further investigation. Objectives: This study determined if at the age of 2 months there were differences in the amount of breast milk consumed, duration of breastfeeding, and infant satiety by infant sex. It also assessed whether infant sex is an independent predictor of initiation of breastfeeding. Methods: This is a secondary analysis of data obtained from the Infant Feeding Practices Survey II (IFPS II) which was a longitudinal study carried out from May 2005 through June 2007 by the Food and Drug Administration and the Centers for Disease Control and Prevention. The questionnaires asked about demography, prenatal care, mode of delivery, birth weight, infant sex, and breastfeeding patterns. A total of 3,033 and 2,552 mothers completed the neonatal and post-neonatal questionnaires respectively. ^ Results: There was no significant difference in the initiation of breastfeeding by infant sex. About 85% of the male infants initiated breastfeeding compared with 84% of female infants. The odds ratio of ever initiating breastfeeding by male infants was 0.93 but the difference was not significant with a p-value of 0.49. None of the other infant feeding patterns differed by infant gender. ^ Conclusion: This study found no evidence that male infants feed more or that their mothers are more likely to initiate breastfeeding. Each baby is an individual and therefore will have a unique feeding pattern. Based on these findings, the major determining factors for breastfeeding continue to be maternal factors therefore more effort should be invested in promoting breastfeeding among mothers of all ethnic groups and social classes.^

Assessing how middle school students' nutrient intake varies based on the availability of a la carte offerings at lunch

Purpose: School districts in the U.S. regularly offer foods that compete with the USDA reimbursable meal, known as `a la carte' foods. These foods must adhere to state nutritional regulations; however, the implementation of these regulations often differs across districts. The purpose of this study is to compare two methods of offering a la carte foods on student's lunch intake: 1) an extensive a la carte program in which schools have a separate area for a la carte food sales, that includes non-reimbursable entrees; and 2) a moderate a la carte program, which offers the sale of a la carte foods on the same serving line with reimbursable meals. ^ Methods: Direct observation was used to assess children's lunch consumption in six schools, across two districts in Central Texas (n=373 observations). Schools were matched on socioeconomic status. Data collectors were randomly assigned to students, and recorded foods obtained, foods consumed, source of food, gender, grade, and ethnicity. Observations were entered into a nutrient database program, FIAS Millennium Edition, to obtain nutritional information. Differences in energy and nutrient intake across lunch sources and districts were assessed using ANOVA and independent t-tests. A linear regression model was applied to control for potential confounders. ^ Results: Students at schools with extensive a la carte programs consumed significantly more calories, carbohydrates, total fat, saturated fat, calcium, and sodium compared to students in schools with moderate a la carte offerings (p<.05). Students in the extensive a la carte program consumed approximately 94 calories more than students in the moderate a la carte program. There was no significant difference in the energy consumption in students who consumed any amount of a la carte compared to students who consumed none. In both districts, students who consumed a la carte offerings were more likely to consume sugar-sweetened beverages, sweets, chips, and pizza compared to students who consumed no a la carte foods. ^ Conclusion: The amount, type and method of offering a la carte foods can significantly affect student dietary intake. This pilot study indicates that when a la carte foods are more available, students consume more calories. Findings underscore the need for further investigation on how availability of a la carte foods affects children's diets. Guidelines for school a la carte offerings should be maximized to encourage the consumption of healthful foods and appropriate energy intake.^

Effectiveness of a nutrition education program for women in a residential program after incarceration

Background: The number of incarcerated women has increased dramatically over the past two decades. During their stay in prison, the medical and nutritional needs of these women are frequently ignored. Overweight or obesity related to poor dietary habits and low-income status are important risk factors for health inequities. Women in this population are at risk for dietary-related chronic diseases such as hypertension, diabetes, and cardiovascular diseases. This is an indication that there is a need for nutrition education in this population. ^ Purpose: The purpose of this study was to provide an evidence-based nutrition education program at a facility for previously incarcerated women in Downtown Houston, Texas (Brigid's Hope). This nutrition education program focused on promoting better health and prevention of chronic diseases by increasing fruit and vegetable (FV) intake and healthy eating on a limited budget. Constructs such as knowledge, skills, self-efficacy, and perceived barriers were evaluated as well as acceptability, feasibility, and sustainability of the program. ^ Methods: The Hope for Health Nutrition Education Program occurred in four weekly sessions at Brigid's Hope. The evaluation design was a one-group quasi-experimental design with pre- and post-test measures. Identical pre- and post-tests were administered before and after the intervention. A total of 11 residents and 2 staff members participated in the study. Results: After four nutrition education sessions, post-tests revealed an overall increase in knowledge, skills, and self-efficacy scores, and decrease in perceived barrier scores towards FV consumption. Changes in skills, self-efficacy, and perceived barriers scores were found to be statistically significant. Participant satisfaction surveys revealed overall high satisfaction of the program and that continuing the program in the future would be possible with support from staff member and mentors. ^ Conclusions: Results from this study show that a nutrition education program can have positive effects towards knowledge, skills, self-efficacy, and perceived barriers towards FV consumption for previously incarcerated women. The high satisfaction for this program shows that a health promotion program with focus on diet and nutrition can play an important role in helping this unique population of women re-enter society.^
