Self-Care Instruments to Measure Nutrition Practices in Children and Parents: Psychometric Analysis.

The purposes of this study were to evaluate the psychometric properties of English and Spanish instruments that measure the nutrition behavior and practices of children and their parents. Orem's self-care deficit nursing theory was used in this methodological study. A convenience sample of 333 children and 262 mothers participated from two schools in Washington, D.C. and two schools in Santiago, Chile. Principal component analysis indicated three component per instrument corresponding to Orem's Theory of operations demonstrating construct validity of the instrument. The study findings showed evidence for validity and reliability of the English and Spanish versions and indicated that the instruments appropriately represented Orem's operations. The results have implications for the development of health behavior measurement instruments that are valid, reliable, designed for children, culturally appropriate, and efficient. Measuring the nutrition behavior of children and parents is critical for determining the effectiveness of nutrition intervention programs. Furthermore, instruments are needed so that researchers can compare corresponding child and parent behaviors or compare behaviors across cultures.

COVID-19 and Morbid Obesity: Associations and Consequences for Policy and Practice.

While the impact of obesity on chronic disease has been widely examined, there has been less research regarding the influence of obesity on infectious diseases, particularly respiratory diseases. This exploratory research uses the currently available data on COVID-19 cases and mortality, along with estimates of the morbidly obese populations in the United States by county, to examine the association between morbid obesity and deaths from COVID-19 and to identify potential coincident spatial clusters of morbid obesity and COVID-19 deaths. Results indicate a statistically significant positive correlation between population-adjusted COVID-19 deaths and cases and the estimated population with a body mass index ≥ 40. Clustering analyses show there is a predominant similarity in the distribution of COVID-19 deaths and obesity. Our findings suggest it is critical to include an awareness of obesity when developing infectious disease control measures and point to a greater need to focus resources toward obesity education and policy initiatives.

Geographic distribution and socio-economic determinants of women's nutritional status in Mali households.

OBJECTIVE: Mali is one of the poorest countries in Africa, with 72% of its population surviving on less than $US 1.00 per day. Health and demographic indicators are bleak. With few exceptions, studies related to the health of women in Mali have largely been under-represented. In addition, in recent years a new type of malnutrition stemming from weight gain and obesity has been observed throughout Africa. The present study aimed to (i) describe geographic and health variations of women of reproductive age, (ii) describe geographic variations of household salt iodine levels and (iii) investigate potential factors associated with women's anthropometric status and use of adequately iodized salt among households in Mali. DESIGN: Demographic and Health Survey data, multistage-stratified cluster sampling methodology. SETTING: Rural and urban areas of Mali. SUBJECTS: Non-pregnant women (n 6015) between the ages of 19 and 44 years. RESULTS: Nineteen per cent of the women were overweight or obese while 11% were underweight. Seventy-eight per cent of the households utilized adequately iodized salt. Underweight women were more prevalent in southern Mali, while obesity was more frequent in the north-east and within the major urban areas. Households located within the southern parts of Mali were more likely to utilize adequately iodized salt. Education, age, modern contraceptive use, breast-feeding status at time of the survey and household wealth index were significantly associated with the women's BMI or households' use of adequately iodized salt. CONCLUSIONS: The combined use of statistical and geographic system analysis contributes to improve targeting of interventions among vulnerable populations.

Maternal-child overweight/obesity and undernutrition in Kenya: a geographic analysis.

OBJECTIVE: The purpose of the study was to examine geographic relationships of nutritional status (BMI), including underweight, overweight and obesity, among Kenyan mothers and children. DESIGN: Spatial relationships were examined concerning BMI of the mothers and BMI-for-age percentiles of their children. These included spatial statistical measures of the clustering of segments of the population, in addition to inspection of co-location of significant clusters. SETTING: Rural and urban areas of Kenya, including the cities of Nairobi and Mombasa, and the Kisumu region. SUBJECTS: Mother-child pairs from Demographic and Health Survey data including 1541 observations in 2003 and 1592 observations in 2009. These mother-child pairs were organized into 399 locational clusters. RESULTS: There is extremely strong evidence that high BMI values exhibit strong spatial clustering. There were co-locations of overweight mothers and overweight children only in the Nairobi region, while both underweight mothers and children tended to cluster in rural areas. In Mombasa clusters of overweight mothers were associated with normal-weight children, while in the Kisumu region clusters of overweight children were associated with normal-weight mothers. CONCLUSIONS: These findings show there is geographic variability as well as some defined patterns concerning the distribution of malnutrition among mothers and children in Kenya, and suggest the need for further geographic analyses concerning the potential factors which influence nutritional status in this population. In addition, the methods used in this research may be easily applied to other Demographic and Health Survey data in order to begin to understand the geographic determinants of health in low-income countries.

Maternal-child nutrition practices and pediatric overweight/obesity in the United States and Chile: a comparative study.

Childhood overweight/obesity is now epidemic in both developed countries and those undergoing economic transition. This study compared maternal and school-age child nutrition practices and body mass index in the United States and in Chile. Children (125 in the United States, 121 in Chile) and their mothers (116 in the United States, 101 in Chile) participated. Findings indicated that child nutrition practices were comparable, but mothers in the U.S. group demonstrated fewer healthy nutrition practices on behalf of their children. Significant associations were found between maternal and child nutrition practices. Substantially more children in the U.S. sample were overweight/obese. Implications for practice are presented.

The growing burden of obesity in Thailand: a review of current trends and policies.

In recent years, there has been a rise in obesity-related diseases in transitional countries. These countries, once plagued with problems related to infectious disease and poverty, now face a dual burden of both chronic and infectious diseases. Thailand has recently experienced significant economic growth, and as a result, the numbers related to obesity and obesity-related diseases have risen significantly. Thailand is an important region to examine the timely issue of obesity-related policy because Thailand has been a model for successful public health interventions and policies throughout Asia. Further, such policies have significant implications for other regions of the world experiencing similar health transitions.

Relación entre prácticas alimentarias reportadas por niños chilenos y preferencias de los padres para su consumo / Relationship between reported dietary practices of Chilean children and their parents preferences for their consumption

The objective of this study was to examine agreement between parental preferences and self-reported food intake in Chilean children. In 2008,152 pairs, of 8 to 13 year old schoolchildren and their parents in Santiago were surveyed. Children self-reported their frequency of consumption of foods from various food groups. Parents reported how often they preferred their children to consume foods from these same food groups. Children reported consuming more sweets, high-calorie snacks, and fruit, and fewer grains than their parents reported preferring them to consume. Girls, 10 and 11 year olds, and children who watched television and used the computer for less than 2 hours per day had dietary patterns most closely aligned with their parents' reported preferences. Children 's dietary reports generally follow parental preferences. Intervention programs should include programs that facilitate parental guidance and encourage children to make healthy food choices at home and in school.

Se estudia concordancia entre preferencias de padres y auto-reporte de niños chilenos en consumo de alimentos. En 2008, se encuestaron 152 escolares ente 8 y 13 años de edad y sus padres, en Santiago, Chile. Los niños reportaron frecuencia de consumo de diferentes grupos de alimentos y los padres, frecuencia con que prefieren que sus hijos los consuman. Los niños informaron mayor consumo de dulces, colaciones altas en calorías y frutas y menor consumo de cereales, que lo declarado por sus padres. Los patrones alimentarios más estrechamente alineados con lo reportado por los padres se observan en: niñas; edades entre 10 y 11 años; ver televisión y utilizar computador menos de 2 horas diarias. En general, lo reportado por niños sigue los patrones de los padres. Programas de intervención debieran incluir guía a padres y estimulo a niños para elegir opciones alimentarias saludables en el hogar y en la escuela.

Maternal prepregnancy body mass index in relation to Hispanic preschooler overweight/obesity.

The aim of the current study was to examine the role of maternal prepregnancy body mass index (BMI) on overweight/obesity among US Hispanic children ages 2 and 4 years old. We used US nationally representative data from preschoolers enrolled in the Early Childhood Longitudinal Study-Birth Cohort study. The findings revealed that a significantly higher percent (41.6%) of Hispanic mothers were overweight/obese prior to pregnancy compared to white mothers (34.8%). At 2 years of age, 38.3% of the children born to Hispanic mothers were overweight/obese compared to 29.4% of children born to white mothers. By the age of 4, overweight/obesity increased significantly for both racial/ethnic groups with preschoolers whose mothers were Hispanic being more likely to be overweight/obese (44.6%) compared to children whose mothers were white (34.2%). Further, preschoolers born to overweight/obese Hispanic mothers were more than twice as likely [odds ratio = 2.74 (95% confidence interval (CI) 1.60, 4.69)] to be overweight/obese than those born to Hispanic mothers of normal prepregnancy BMI. Preschoolers born to overweight/obese white mothers were approximately 1.4 (95% CI 1.05, 1.93) times more likely to be overweight/obese in comparison to those born to mothers with a normal prepregnancy BMI. Maternal prepregnancy weight is potentially a modifiable risk factor for preschooler overweight/obesity. Study findings support the design of early and targeted interventions to reduce this risk to the long-term health of Hispanic maternal and child dyads.

Maternal obesity, health status during pregnancy, and breastfeeding initiation and duration.

OBJECTIVE: The purpose of this study was to determine whether maternal prepregnancy overweight/obesity has independent effects on breastfeeding initiation and duration and whether these effects are different for women who experience medical problems during pregnancy or labor/delivery complications in comparison with those who have no medical or labor/delivery complications. METHODS: We used the early childhood longitudinal study-birth cohort data. Kaplan-Meier survival functions, logistic, and Cox regression modeling were used in the analyses. RESULTS: Findings indicate that overweight/obese women with medical or labor/delivery complications were less likely to initiate breastfeeding in comparison with their counterparts of normal weight. We did not find an independent effect of prepregnancy overweight/obesity on breastfeeding initiation among women with no medical problems. This group of women, however, had an 11% increased risk of stopping breastfeeding with each additional month of breastfeeding duration in comparison to those of normal weight. CONCLUSIONS: It is important to evaluate the health history and pregnancy complications among overweight/obese mothers in developing interventions for successful initiation and duration of breastfeeding.

Sociodemographic determinants of growth among Malian adolescent females.

In Africa, research concerning the social determinants of poor nutritional status has typically focused on children under 5 years of age and has used defined categorical boundaries based on international reference standards. In this article, stunting and wasting of 1,157 Malian adolescent girls is measured through both categorical and continuous data. The focus on adolescent girls is significant because there is relatively little literature examining this group, and because adolescence marks the time when girls gain greater workload responsibilities, autonomy of food choices, and, as a result of the adolescent growth spurt, require the greatest amount of caloric intake respective to their weight since infancy. To differentiate stunting and wasting causes, a number of socioeconomic, geographic, and demographic factors are explored. The findings suggest that continuous data provides a basis for modeling stunting and wasting superior to utilizing international reference categories. Estimations show that decreasing age, the presence of servants, a greater number of wives in a compound, and residence in a large urban area correlate with improved nutritional status while wealthier families appear to correlate with greater stunting and wasting, and no correlation exists with estimated energy expenditure. Future studies should incorporate continuous data, and the need exists for greater analysis of social determinants of growth indicators among adolescent females. Further, these findings have significant implications in the development of nutrition intervention programs aimed at the vulnerable population in Mali, leading us to conclude that factors beyond socioeconomic indicators such as household structure and location should be more fully examined.

A cross-sectional examination of growth indicators from Thai adolescent girls: evidence of obesity among Thai youth?

BACKGROUND: Few studies have examined growth data from adolescent girls in Southeast Asia and almost none have been carried out in Thailand. Thus this study examines growth data from Thai adolescent girls. AIM: Cross-sectional growth data from a sample of Thai girls were compared to reference data from healthy well-nourished girls. It is hypothesized that the reference girls will be taller and heavier than the Thai girls; however, the growth indicators will also indicate that obesity is present among Thai girls. SUBJECTS AND METHODS: Anthropometric and age at menarche data were collected from a sample of 319 adolescent girls ages 11-17 years living in suburban Thailand. RESULTS: Thai girls are heavier than the reference girls at ages 11-13 years yet are shorter and lighter than the reference girls at ages 14-17 years. The data also reveal that 18.4% of the girls are overweight or obese as classified by the CDC BMI-for-age percentile growth curves. CONCLUSION: The findings suggest the presence of overweight and obesity among this adolescent Thai population. These data may reflect the impact of the improved economic situation of Thailand as well as the impact of body image concerns among these young girls.

Classification tree analysis of stunting in Malian adolescent girls.

This study examines relationships between growth data and energy expenditure, economic status, and family structure among Malian adolescent girls, aged 10-17 years living in the Segou Region of Mali. Classification and regression trees (CART) were used as the primary methodology to identify high-risk subgroups for stunting (measured as height-for-age) in a sample of 1,103 Malian adolescents. Because CART has been used rarely to examine growth and development, this study provides a new way to better understand how economic status, family structure, and energy expenditure related factors influence stunting in Mali. The findings indicate that the greater the number of sisters and women in a household, the poorer the nutritional status of adolescent girls. The data also show that the presence of servants within the household may predict better nutritional success of young girls. Energy expenditure was an important predictor in the context of family structure regarding the number of sisters and the presence of servants. Wealth indicators did not appear in the final tree, suggesting that wealth may not play as great a role in predicting poor growth and nutritional status as family size and structure. In conclusion, classification trees may assist in understanding the interactive nature of predictive factors of stunting in this population, and further provide evidence for intervention programs aimed at improving the health and nutritional status of Malian adolescent girls.

Mixed-longitudinal analysis of growth data from Malian adolescent girls: evidence for compensatory gain?

Cross-sectional data have previously indicated poor growth and development among adolescent girls in Mali. These data have shown that Malian girls are shorter and lighter than their United States female counterparts. Many studies suggest that this evidence of poor growth and development is due to a combination of poor nutrient intake, high-energy expenditure, and poor access to health care. At adolescence, individuals rarely follow a standard pattern of growth due to different biological timetables and expressions of pubertal growth. By examining velocity of growth, researchers can recognize developmental patterns such as compensatory gain. This study examines the growth rates of Malian girls over a 6-month period. Anthropometric data were collected from a total of 1,045 adolescent girls ages 10-17 years. Height and weights were collected twice from the Segou Coura community in the town of Segou and from the Dioro Arrondissement in 1997. From these data, mixed longitudinal analyses were conducted. Both the height and weight velocity data showed patterns of delayed growth rates when compared with American girls. Although Malian girls are similar to American girls in that they tend to reach their peak height velocity at age 12, the Malian girls demonstrate a longer growth spurt than the American girls. This evidence of greater height velocity may be an indication of compensatory growth, or compensatory gain, and is partially supported from cross-sectional data. While these Malian data do not show much evidence that certain stressors are relieved during adolescence, only more extensive longitudinal data can more fairly examine the issue.

Physical activity and body composition analysis of female baccalaureate nursing students.

Although nursing students are educated about the importance of healthy diets and the benefits of exercise, many do not engage in health promotion behaviors. This study longitudinally examined specific indicators of obesity among a group of female nursing students who incorporated an exercise program into their normal weekly routine. Indicators for obesity were identified using anthropometric data that included weight, body mass index (BMI), and percentage of body fat. Blood pressure, pulse data, and a physical activity level assessment were performed at the beginning and at the conclusion of the study period. Results indicated improvement in overall body composition, including a reduction in percent body fat and BMI. Students also showed improved physical activity levels. Since nurses need to counsel clients on primary prevention issues such as physical activity and maintaining ideal body weight and lean mass, the importance of positive health behaviors for nursing students and nurses cannot be stressed enough.

Growth and development of adolescent girls from the Segou Region of Mali (West Africa).

In Mali, adolescent girls face many physical stresses which, with a history of poor nutrition, can result in delayed growth and development. Despite the fact that adolescent girls encounter nutritional demands, most research in Mali has focused only on young children. This study examines anthropometric and reproductive data on 1,056 adolescent girls (aged 10-17 years) from the Segou Region of Mali. When compared to the reference population, the Malian girls exhibited poorer indicators of growth and development. Z-scores for height-for-age and weight-for-age were below 0 at all ages. Urban girls had better indicators of growth than rural girls. The body composition data show that the Malian girls have lower body fat than reference girls. Menarche was delayed by about 1.5 years compared to girls from the United States and Europe. Delayed growth and development may be due to many factors, including a history of undernutrition, poor socioeconomic status, and increased energy demands.
