Lack of calcium rich foods in the diet, low knowledge on calcium level recommendations and severe food insecurity predicts low calcium intake among Vietnamese women.

OBJECTIVE: To assess nutrition knowledge related to osteoporosis and calcium, osteoporosis health beliefs, dietary calcium intake and household food insecurity among adult women in Vietnam. METHODS: Two hundred fifty-one women aged 30-65 years living in a rural district in Hanoi -Vietnam were recruited. A questionnaire was used to collect information on nutrition knowledge related to osteoporosis and calcium intake, health beliefs, household food security, and dietary calcium intake. Data analysis included descriptive statistics and regressions. RESULTS: Majority of the participants did not know calcium recommendations (95%) and recommended daily servings of calcium-rich foods (60%). In addition, majority of the participants (83.7%) were not aware of osteoporosis risk factors. Slightly less than half of the participants (46.2%) reported that they would have difficulties changing their current diets to consume more calcium rich foods. Half of the participants (50.4%) reported being food insecure, with 22% of them reporting having severe food insecurity. Mean dietary calcium intake was 534.5 mg/day, of which milk and dairy products contributed only 4%. Nutrition knowledge, perceived benefits, and self-efficacy were positively associated with calcium intake (p < 0.05); whereas perceived barriers and severe food insecurity were significantly associated with low dietary calcium intake (p < 0.05). CONCLUSIONS: The results of this study showed calcium intake among the participating Vietnamese women was lower than the national recommendation, indicating the need for nutrition programs and promotions to increase calcium intake. These programs should aim at increasing awareness on national calcium recommendations and skills to obtain and consume calcium-rich foods while considering development of safety nets for food insecure households, as pertaining to adequate dietary calcium intake.

Factors that contribute to effective online nutrition education interventions: a systematic review.

CONTEXT: The use of the internet and technology as a medium for delivering online nutrition education (ONE) has increased; however, evidence-based studies exploring factors that contribute to best practices in online interventions have not emerged. OBJECTIVE: The purpose of this systematic review was to identify factors that contributed to successful ONE interventions in relation to research studies published between 2009 and 2018. DATA SOURCES: Following the PRISMA guidelines, relevant studies were identified through PubMed, Medline, Web of Science, Science Direct, and Education Resources Information Center (ERIC) databases. DATA EXTRACTION: Five authors screened and determined the quality of the studies using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system and extracted the data from the articles. DATA ANALYSIS: Twenty-seven studies were included: 21 studies were website-based, 3 were delivered through smartphone application, 2 were delivered as online courses, and 1 used text messages. Tailored messages/feedback, interaction between participants and investigators, identification of specific behaviors, use theory, adequate duration, and alignment between stated objectives and activities were factors that contributed to successful online interventions, while comparison bias and the lack of specific details on duration and dosage, tracking system, objective outcome measurements, and follow-up were factors that may have interfered with successful ONE interventions. CONCLUSIONS: The findings underscore the importance of developing ONE intervention designs that utilize factors unique to online platforms for effective interventions aimed at behavior change.

Factors that contribute to effective nutrition education interventions in children: a systematic review.

Context: Establishing healthy dietary practices at an early age is crucial, as dietary behaviors in childhood track to adulthood. Objective: The purpose of this systematic review was to identify factors associated with successful nutrition education interventions conducted in children and published between 2009 and 2016. Data Sources: Using the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guidelines, relevant studies were identified through the PubMed, Web of Science, ScienceDirect, and ERIC (Educational Resources Information Center) databases. Study Selection: Studies published in English between 2009 and 2016 that included a nutrition education intervention among children aged 2 to 19 years were included. Review articles, abstracts, qualitative or cross-sectional studies, and studies targeting children with special nutritional needs were excluded. Data Extraction: Four authors screened and determined the quality of the studies using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) system and extracted the data from the articles. Data Analysis: Forty-one studies were included: 7 targeted preschool children, 26 targeted elementary school children, and 8 targeted secondary school children. A total of 46% met their primary objectives of nutrition education intervention, while the rest either partially achieved or did not achieve their stated objectives. Results: Successful interventions targeting school children engaged parents by means of face-to-face sessions, identified specific behaviors to be modified, and assured fidelity by training teachers or recruiting trained experts to deliver the intervention. In addition, they allowed adequate dosage, with an intervention duration of at least 6 months, and used age-appropriate activities. Conclusions: Interventions with a multicomponent approach that were age appropriate and of adequate duration (≥ 6 months), that engaged parents, and that ensured fidelity and proper alignment between the stated objectives, the intervention, and the desired outcomes were more likely to succeed.

Effective nutrition education and communication for sustainable maternal and child health.

Maternal and child health (MCH) consists of an interdependent reproductive system that collectively determines the survival of the mother during childbirth, and determines the health and survival of the child. This interdependency underscores the importance of appropriate and timely interventions during pregnancy through the first 1000 d at the minimum. The Millennium Development Goals (MDG) recommended the use of the continuum of care for the development of interventions by addressing all the stages of MCH. The purpose of the present paper is to review the factors that contributed to the attainment of the MDG 4 and MDG 5 by analysing the interventions conducted by the countries that achieved at least 5·0 and 5·5 %, respectively, and determine the level of their intervention based on the MCH conceptual framework. Out of the eighteen selected countries discussed, fifteen countries achieved their target for either MDG 4 or MDG 5 or both, while three countries did not achieve their target. The countries that were more likely to achieve their targets addressed the societal, underlying and direct causes, and implemented country wide policies. In contrast, the countries that did not succeed were more likely to address the direct causes with poor policy implementation. Understanding the motivation and limitations of the target population, including nutrition education and targeting behaviour change has the potential to result in sustainable MCH. This information has the potential to enlighten the policymakers as we progress to the sustainable development goals, specifically goals 2 and 3.

Factors Influencing Efficacy of Nutrition Education Interventions: A Systematic Review.

OBJECTIVE: To examine systematically factors that contribute to the efficacy of nutrition education interventions in promoting behavior change for good health based on their stated objective. In a departure from previous reviews, the researchers investigated factors that lead to success of various types of interventions. Critical analysis of these factors constituted the outcome of this review. METHODS: This study followed Preferred Reporting Items for Systematic Reviews and Meta-analysis criteria. A total of 246 original articles published between 2009 and 2015 in PubMed, Medline, Web of Science, Academic Search Complete, Science Direct, Cochrane Reviews, ERIC, and PsychLIT were initially considered. The number was screened and scaled down to 40 publications for the final analysis. Quality assessment was based on the Cochrane Handbook for Systematic Reviews of Intervention. Studies were rated as having low risk of bias, moderate risk, or high risk. RESULTS: Efficacy of nutrition education interventions depended on major factors: interventions that lasted ≥5 months; having ≤3 focused objectives; appropriate design and use of theories; fidelity in interventions; and support from policy makers and management for worksite environmental interventions. CONCLUSIONS AND IMPLICATIONS: Intervention duration of ≥5 months, ≤3 focused objectives, randomization, use of theories, and fidelity are factors that enhance success of interventions based on the results of this study.

Prevalence of Food Insecurity in Low-Income Neighborhoods in West Texas.

OBJECTIVE: To determine the prevalence of food insecurity and the coping strategies and to investigate the role of safety nets among low-income households in urban and rural west Texas. DESIGN: The Core Food Security Module, an 18-item scale, was used in a cross-sectional purposeful convenience sample comparing rural and urban households, whereas the demographic survey assessed participation in food assistance/safety net programs. SETTING: Rural and urban neighborhoods in west Texas. PARTICIPANTS: Sample size of 191 participants from low-income households, predominantly African American and Hispanic people. MAIN OUTCOMES MEASURES: Levels of food insecurity and use of safety nets. ANALYSES: Comparisons between rural and urban households and between food-secure and food-insecure households were analyzed using the chi-square test of independence for categorical variables. Fisher's exact test was used whenever the number in each cell was < 5 in 2 × 2 contingency tables. RESULTS: Prevalence of household and child food insecurity in west Texas was 63% and 43%, respectively. Forgoing balanced meals was a common coping strategy. There was high intake of affordable energy-intense foods. CONCLUSIONS AND IMPLICATIONS: The high prevalence of food insecurity in low-income households in west Texas led to high intake of energy-intense food with low nutrients, resulting in higher prevalence of anemia, obesity, and other chronic diseases. There was low participation in safety net programs. Educational interventions on food choices are recommended.

Multiple point-of-testing nutrition counseling sessions reduce risk factors for chronic disease among older adults.

The objectives of this study were to explore the relationships of baseline dietary intakes and frequency of attendance at point-of-testing nutrition counseling sessions to selected risk factors for chronic diseases during a 3-year intervention. This study was part of a large multidisciplinary, community-based health outreach project conducted in a rural community of northern Louisiana. Screenings, point-of-testing counseling, weekly group exercise sessions, and group nutrition education sessions were provided over a period of 3 years. Outcome variables assessed at 6-month intervals over 3 years were body mass index (BMI), systolic and diastolic blood pressure, fasting blood glucose, and total and LDL cholesterol and dietary intake. Repeated measure analysis of variance was used to investigate the impact of the frequency of counseling sessions on outcome variables. Paired t-tests were used to identify points at which significant changes occurred. A total of 159 subjects ages 65 years and older participated in this study. The majority of the participants were female (62%) and White (82%). Attending the point of testing counseling for more than two sessions was important for a significant improvement in BMI (p ≤ 0.001), LDL cholesterol (p ≤ 0.03), blood glucose (p ≤ 0.03), and diastolic blood pressure (p ≤ 0.045). Participants who attended at least three sessions had significant reductions in risk factors for obesity and related chronic diseases, underscoring the importance of follow-up sessions after health screening.

Practicing preventive health: the underlying culture among low-income rural populations.

CONTEXT: Health disparities on the basis of geographic location, social economic factors and education levels are well documented. However, even when health care services are available, there is no guarantee that all persons will take preventive health measures. Understanding the cultural beliefs, practices, and lifestyle choices that determine utilization of health services is an important factor in combating chronic diseases. PURPOSE: The purpose of this study was to investigate personal, cultural, and external barriers that interfered with participating in a community-based preventive outreach program that included health screening for obesity, diabetes, heart diseases, and hypertension when cost and transportation factors were addressed. METHODS: Six focus groups were conducted in a rural community of Louisiana. Focus groups were divided into 2 categories: participants and nonparticipants. Three focus groups were completed with Dubach Health Outreach Project (DUHOP) participants and 3 were completed with nonparticipants. The focus group interviews were moderated by a researcher experienced in focus group interviews; a graduate student assisted with recording and note-taking during the sessions. FINDINGS: Four main themes associated with barriers to participation in preventive services emerged from the discussions: (1) time, (2) low priority, (3) fear of the unknown, and (4) lack of companionship or support. Health concerns, free services, enjoyment, and free food were identified as motivators for participation. CONCLUSIONS: The findings of this study indicated that the resulting synergy between low-income status and a lack of motivation regarding health care prevention created a complicated practice of health care procrastination, which resulted in unnecessary emergency care and disease progression. To change this practice to proactive disease prevention and self care, a concerted effort will need to be implemented by policy makers, funding agents, health care providers, and community leaders and members.
