Abstract Objectives The purpose of this study was to conduct a systematic review to assess criterion-related validity of spectroscopy-based skin carotenoid measurements against serum/plasma carotenoids and/or dietary intake of fruit and vegetables. Methods PubMed, Embase, ProQuest, Cumulative Index of Nursing and Allied Health Literature, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials were systematically searched in December 2018 to identify articles for inclusion. Articles published from 1990–2018 that correlated spectroscopy-based skin carotenoid measurements to blood carotenoids and/or fruit and vegetable intake met inclusion criteria. The articles were reviewed independently by at least two authors and discrepancies were mediated by a third author. A hand search was conducted of the included papers to ensure no relevant articles were excluded. Results Of the 7931 articles identified in the literature search, 54 articles met the eligibility criteria for full-text review. Following the full-text review, 22 articles were selected for data extraction and were included in the present review. Following the hand search, seven additional articles were eligible for inclusion, resulting in a total of 29 articles. All 29 articles demonstrated statistically significant correlations between spectroscopy-based skin carotenoid measurements and serum/plasma carotenoids and/or dietary intake of fruits and vegetables. Three methods of spectroscopic detection were used: 20 articles used resonance Raman spectroscopy (RRS), seven articles used spectrophotometers, and two articles used reflection spectroscopy (RS) to measure skin carotenoids. Twenty of the articles described the racial/ethnic demographics of the study population, with seven articles containing more than 20% from a non-white, minority population. Four studies were conducted with infants, six studies included children, and the remaining 19 studies focused on adults. Conclusions The results of the systematic review support the use of spectroscopy-based skin carotenoid measurements as an alternative measure of fruit and vegetable intake. Additional research is warranted to examine the use of different spectroscopy techniques in diverse populations and populations of varying ages. Funding Sources N/A.

BACKGROUND There has been a proliferation of digital health interventions (DHIs) targeting dietary intake. Despite their potential, the effectiveness of such interventions are thought to be dependent, in part, on user engagement. However, the relationship between engagement and the effectiveness of dietary DHIs is not well understood. OBJECTIVE As such, the aim of this systematic review is to describe the association between DHI engagement (both usage and subjective experience) and dietary intake. METHODS A comprehensive search for peer-reviewed literature was undertaken in four electronic databases (EMBASE, MEDLINE, PsychINFO, Scopus) from inception to December 2019. A hand search of targeted journals, grey literature searches and a search of relevant references of similar reviews was also conducted. Studies were eligible if they examined a quantitative association between objective measures of engagement with a DHI (subjective experience or usage) and measures of dietary intake in adults (aged ≥18 years). Authors single screened studies, with a pair of review authors assessing quality of studies and extracting relevant data. Narrative syntheses using vote counting was undertaken to explore to relationship between measures of engagement and dietary intake. RESULTS The search resulted in 10,653 citations, of which seven studies (from nine articles) were included in the review. The majority of studies (n=5) included usage measures of engagement rather than subjective experience (n=2). Logins were the most commonly reported usage measure (n=5 studies), and fruit and vegetable intake was the most common measure of dietary intake (n=4 studies). The heterogeneity of engagement and dietary intake measures limited the use of meta-analytic techniques, however narrative review (vote counting) found mixed evidence of an association with usage measures (5 of 12 associations indicating a positive relationship, 7 were inconclusive). No evidence regarding an association with subjective experience was found (0 of 2 associations were inconclusive). The majority of included studies (n=5) were rated poor quality according to the Newcastle Ottawa Scale. CONCLUSIONS The findings provide some evidence supporting an association between measures of usage and fruit and vegetable intake, however this was inconsistent. No evidence was found regarding an association with subjective experience. Given the limited number of studies included in the review and poor quality of available evidence further research examining the association between DHI engagement and dietary intake using consistent measures, with an additional focus on subjective experience is warranted.

Behavioural Interventions

Poor eating habits are common during young adulthood and influence chronic disease morbidity. This systematic review evaluates the effectiveness of interventions aiming to improve dietary intake among young adults and, identifies which behaviour change techniques (BCTs) are most effective. Six electronic databases were searched for RCTs published until October 2018, and evaluating behavioural interventions assessing change in dietary intake in young adults (17–35 years). Of the 18,779 articles identified, 54 were included. Forty studies focused on fruit and/or vegetable intake, of which 63% showed a significant between-group difference in favour of the intervention group. Meta-analysis (n = 17) demonstrated a significant increase in fruit and vegetable intake of +68.6 g/day after three months of intervention and +65.8 g/day for interventions >3 months when compared to control. A meta-analysis (n = 5) on total energy intake found no significant differences between groups. The BCTs with the highest effectiveness ratio were habit formation (100%), salience of consequences (83%) and adding objects to the environment (70%). The review highlights the potential of behavioural interventions to improve young adults’ fruit and vegetable intake but was less convincing for other dietary outcomes. Due to the lack of studies including each BCT, the BCTs imperative to success could not be identified.

Abstract Objectives To describe and compare fruit and vegetable intake by level of variety among children in What We Eat in America (WWEIA), NHANES. Methods One-day dietary intake data of children 2–19 years (N = 5920) in WWEIA, NHANES 2013–2016 were used. Fruit and vegetable (FV) variety was the count of foods consumed that contributed to total FV intake. To be counted, at least 0.1 cup equivalent (CE) FV of each single FV item and 0.2 CE FV from a mixed dish had to have been consumed. Each FV was counted only once; a mixed dish counted as one. The Food Patterns Equivalents Database was used to determine the CE of FV intake. Individuals were classified for variety of intake as High (H) (5 + items); Moderate (M) (3–4 items); Low (L) (1–2 items). Percentage contribution of WWEIA Food Categories to FV intake was estimated. Differences in FV intakes between variety levels were compared by t-test. Those with a count of ‘0’ (N = 466) were excluded. Results Percentage of children in each variety level was: H: 15, M: 33; L: 44; none: 8%. Mean FV intakes (CE/1000 kcal) by variety level were H: 1.9; M: 1.4; L: 0.8 (P < 0.001). Distributions of 2–5y, 6–11y and 12–19y, respectively among variety levels were: H: 18, 16, 13%; M: 40, 32, 30%; L: 37, 44, 48%; none: 6, 8, 9%. For H, M, and L levels, respectively, fruit variety counts were 2.5, 1.5, and 0.5, and vegetable variety counts were 3.5, 2, and 1 (P < 0.001). Among all 2–19y, single FV items (excl 100% juice) contributed 64% to FV intake of the H vs M (55%) and L (50%), whereas Mixed Dishes contributed 12% to intake of H vs M (15%) and L (21%). The percentages of H, M and L groups reporting intake from WWEIA Food Categories were 89, 65 and 40 for Vegetables; 86, 65, and 35 for Fruit; and 79, 79, and 77 for Mixed Dishes. Conclusions FV variety was highest for very young children and lowest among adolescents. Children with more variety of FV intake were more likely to include single FV and in higher amounts than those with less FV variety. These results support suggestions for boosting FV intake of children by encouraging their consumption at snacks and including vegetable side dishes at meals. Funding Sources ARS-USDA.

Path Analyses

Diabetes and heart disease disproportionately burden African Americans, who tend to have worse nutritional intake than Whites. Many Black churches are influential institutions in the Black community, with potential to assist with promotion of healthy eating behaviors. The purpose of the current study was to use the Theory of Planned Behavior (TPB) to examine intention to eat a healthy diet and dietary behaviors among church-affiliated African Americans. It was hypothesized that TPB constructs would positively predict intention to eat a healthy diet and that intention to eat a healthy diet would be a predictor of fat and fruit and vegetable intake. It was also hypothesized that control beliefs would predict reduced fat intake and increased fruit and vegetable intake. Path analyses indicated behavioral, normative, and control beliefs were predictive of intention to eat a healthy diet. Intention to eat healthy was a significant predictor of dietary intake behaviors. These findings provide support for the use of the TPB in examining diet among church-affiliated African Americans. This study represents an opportunity to inform dietary interventions for the African American faith community.

The Impact

Abstract Objectives Vouchers 4 Veggies (V4V) is a transformative healthy food voucher program aimed at increasing access to and affordability of healthy food in the most vulnerable communities. Between 2015–2018, over 2600 ethnically diverse low-income individuals were enrolled in the program with the goal to increase their fruit and vegetable intake, improve food security status and change health perception. Methods V4V partners with local community-based organizations and clinics that serve as voucher distribution sites as well as neighborhoods stores, grocery stores, and famer's markets where participants can redeem their vouchers. Participants receive $20-$40 worth of vouchers per month for 6 months. Data for this evaluation were collected using pre- and post- surveys (at 0 and 4–6 months) that included a validated fruit and vegetable intake screener, the USDA 7-item food security screener, demographic questions and health perception questions. Results Data from 862 matched surveys indicate that mean fruit and vegetable intake increased from 2.49 to 3.52 servings daily, corresponding to a 1.03 servings increase after six months in the program (0.89,1.77; P < .001). In addition, V4V participants’ food security scores improved, decreasing 0.88 points (−1.07, −0.71; P < 0.001) on a 6 point scale (0 being the most food secure and 6 being very food insecure), from a mean of 5.53 to 4.65 using the USDA validated 6-item scale. When stratified by race, food security improved significantly for all major racial groups except Black/African Americans. Finally, participants reported a statistically significant improvement in self-reported health status (P < 0.001), with a 14% change in status from poor/fair health to good/very good/excellent health. Conclusions This evaluation suggests that a modest supplement for fruits and vegetables may be able to improve dietary intake, support food security, and improve health perception among vulnerable residents of San Francisco. More research is needed to understand differences in maintaining long-term health and behavior changes among program participants. Funding Sources V4V received funding from the SF Department of Public Health, Hellman Foundation, AARP Foundation, and Kaiser Permanente Community Benefits Program.
