Acceptability of a text message-based intervention for obesity prevention in infants from Hawai'i and Puerto Rico WIC

Interventions with pregnant women, new mothers and other primary caregivers for preventing early childhood caries

BACKGROUND

Dental caries, a common chronic disease of childhood, is associated with adverse health and economic consequences for infants and their families. Socioeconomically disadvantaged children have a higher risk of early childhood caries (ECC). This review updates one published in 2019.

OBJECTIVES

To assess the effects of interventions undertaken with pregnant women, new mothers or other primary caregivers of infants in the first year of life, for preventing ECC (from birth to six years).

SEARCH METHODS

We searched Cochrane Oral Health's Trials Register, Cochrane Pregnancy and Childbirth's Trials Register, CENTRAL, MEDLINE (Ovid), Embase (Ovid), CINAHL EBSCO, the US National Institutes of Health Ongoing Trials Register (clinicaltrials.gov) and WHO International Clinical Trials Registry Platform (apps.who.int/trialsearch). The latest searches were run on 3 January, 2023.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing interventions with pregnant women, or new mothers and other primary caregivers of infants in the first year of life, against standard care, placebo or another intervention, reporting on a primary outcome: caries presence in primary teeth, dmfs (decayed, missing, filled primary surfaces index), or dmft (decayed, missing, filled teeth index), in children up to six years of age. Intervention types include clinical, oral health promotion/education (hygiene education, breastfeeding and other dietary advice) and policy or service.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed study eligibility, extracted data, assessed risk of bias, and assessed certainty of evidence (GRADE).

MAIN RESULTS

We included 23 RCTs (5 cluster-randomised), involving 25,953 caregivers (mainly mothers) and their children. Fifteen trials assessed oral health education/promotion interventions against standard care. Six trials assessed a clinical intervention for mother dentition, against placebo, or a different type of clinical intervention. Two trials assessed oral health/education promotion plus clinical intervention (for mother's dentition) against standard care. At most, five trials (maximum of 1326 children and 130 mothers) contributed data to any comparison. Enamel-only caries were included in the diagnosis of caries in some studies. For many trials, the risk of bias was unclear due to lack of methodological details reported. In thirteen trials, participants were socioeconomically disadvantaged. No trial indicated receiving funding that was likely to have influenced their results. Oral health education/promotion interventions Child diet and feeding practice advice versus standard care: We observed a probable 15 per cent reduced risk of caries presence in primary teeth with the intervention (RR 0.85, 95% CI 0.75 to 0.97; 3 trials; 782 participants; moderate-certainty evidence), and there may be a slightly lower mean dmfs (MD -0.29, 95% CI -0.58 to 0; 2 trials; 757 participants; low-certainty evidence); however, the evidence is very uncertain regarding the difference between groups in mean dmft (MD -0.90, 95% CI -1.85 to 0.05; 1 trial; 340 participants; very low-certainty evidence). Breastfeeding promotion and support versus standard care: We observed little or no difference between groups in the risk of caries presence in primary teeth (RR 0.96, 95% CI 0.89 to 1.03; 2 trials; 1148 participants; low-certainty evidence) and in mean dmft (MD -0.12, 95% CI -0.59 to 0.36; 2 trials; 652 participants; low-certainty evidence). dmfs was not reported. Child diet advice compared with standard care: We are very uncertain about the effect on the risk of caries presence in primary teeth (RR 1.08, 95% CI 0.34 to 3.37; 1 trial; 148 participants; very low-certainty evidence). dmfs and dmft were not reported. Oral hygiene, child diet and feeding practice advice versus standard care: The evidence is very uncertain about the effect on the risk of caries presence in primary teeth (RR 0.73, 95% CI 0.50 to 1.07; 5 trials; 1326 participants; very low-certainty evidence) and there maybe little to no difference in mean dmfs (MD -0.87, 95% CI -2.18 to 0.43; 2 trials; 657 participants; low-certainty evidence) and mean dmft (MD -0.30, 95% CI -0.96 to 0.36; 1 trial; 187 participants; low-certainty evidence). High-dose versus low-dose vitamin D supplementation during pregnancy: We are very uncertain about the effect on risk of caries presence in primary teeth (RR 0.99, 95% CI 0.70 to 1.41; 1 trial; 496 participants; very low-certainty evidence). dmfs and dmft were not reported. Clinical interventions (for mother dentition) Chlorhexidine (CHX, a commonly prescribed antiseptic agent) or iodine-NaF application and prophylaxis versus placebo: We are very uncertain regarding the difference in risk of caries presence in primary teeth between antimicrobial and placebo treatment for mother dentition (RR 0.97, 95% CI 0.80 to 1.19; 3 trials; 479 participants; very low-certainty evidence). No trial reported dmfs or dmft. Xylitol compared with CHX antimicrobial treatment: We are very uncertain about the effect on caries presence in primary teeth (RR 0.62, 95% CI 0.27 to 1.39; 1 trial, 96 participants; very low-certainty evidence), but we observed there may be a lower mean dmft with xylitol (MD -2.39; 95% CI -4.10 to -0.68; 1 trial, 113 participants; low-certainty evidence). No trial reported dmfs. Oral health education/promotion plus clinical interventions (for mother dentition) Diet and feeding practice advice for infants and young children plus basic dental care for mothers compared with standard care: We are very uncertain about the effect on risk of caries presence in primary teeth (RR 0.44, 95% CI 0.05 to 3.95; 2 trials, 324 participants; very low-certainty evidence) or on mean dmft (1 study, not estimable). No trial reported dmfs. No trials evaluated policy or health service interventions.

AUTHORS' CONCLUSIONS

There is moderate-certainty evidence that providing advice on diet and feeding to pregnant women, mothers or other caregivers with children up to the age of one year probably leads to a slightly reduced risk of early childhood caries (ECC). The remaining evidence is low to very-low certainty and is insufficient for determining which, if any, other intervention types and features may be effective for preventing ECC, and in which settings. Large, high-quality RCTs of oral health education/promotion, clinical, and policy and service access interventions, are warranted to determine the effects and relative effects of different interventions and inform practice. We have identified 13 ongoing studies. Future studies should consider if and how effects are modified by intervention features and participant characteristics (including socioeconomic status).

E-health Dietary Interventions for Participants of SNAP and WIC: A Systematic Review

The migration of federal assistance services to online platforms during the COVID-19 pandemic sparked interest in digital nutrition education for individuals participating in the Supplemental Nutrition Assistance Program (SNAP) and Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) programs. With federal government investing in the modernization of the nutrition education components of both programs, there is a need to identify science-backed electronic health (e-health) dietary interventions to improve health outcomes in this population. Therefore, the objective of this systematic literature review was to summarize the effectiveness, acceptability, and feasibility of e-health dietary interventions among individuals participating in WIC or SNAP. Keyword searches were performed in Google Scholar, PubMed, and Science Direct. The search included peer-reviewed literature from 2014 to 2023 and a few articles offering context about interventions used long-term by the nutrition assistance programs. PRISMA guidelines were followed to conduct this systematic literature review, which resulted in 36 articles eligible for extraction. The studies evaluated e-health (52.8%), short message service/text messaging (27.8%), and smartphone application interventions (19.4%) delivered to WIC or SNAP participants. The interventions identified aimed to modify food choice, eating behavior, and dietary intake among SNAP participants, SNAP-eligible adults, and WIC participants. Most interventions were developed using content delivery and health behavior theoretical frameworks (77.8%) and evidence-based nutritional recommendations (59.3%). Review findings show a high level of acceptability and feasibility for e-health and mobile health dietary interventions among WIC and SNAP participants but varying levels of effectiveness. Level of engagement, dosage, retention, and adherence were strong predictors of positive dietary behavior change regardless of the mode of intervention delivery. Future studies need to prioritize health equity by recruiting samples representative of food nutrition assistance participants and addressing digital health literacy as a potential barrier to intervention effectiveness, as none of the present studies measured literacy among participants.

Formula Feeding Is Associated with Rapid Weight Gain between 6 and 12 Months of Age: Highlighting the Importance of Developing Specific Recommendations to Prevent Overfeeding

We examined differences in mean daily calorie intake and rapid weight gain risk among 6- to 12-month-old infants by milk feeding status: breastmilk only, breastmilk and formula (combined), or formula only. Another objective was to determine what frequency and amount of formula fed were associated with overfeeding among infants. Mother-infant dyads (n = 240) were recruited from a pediatric clinic mainly serving Medicaid recipients. At 6, 9, and 12 months of infants' age, 24 h feeding recalls were conducted using the multiple-pass method. Infant weight measurements were accessed from clinic records to estimate rapid weight gain between 6 and 12 months. Among the participants, 82% received WIC. More than half of the participants were either African American or Latino by race/ethnicity. Calorie intake among formula-only fed infants was higher than in the other two milk feeding groups. One-fourth of the infants were experiencing rapid weight gain, and the risk was 3-fold higher among formula-only fed infants. Exceeding daily calorie requirements or overfeeding was associated with both formula amount and the frequency of feeding (p < 0.01). Specific guidelines and education on formula feeding practices are critical to prevent accelerated growth among infants. Gaining further understanding on parenting style and formula feeding practices is also warranted.

Feasibility, Acceptability, and Initial Efficacy of a Digital Intervention to Improve Consumption of Foods Received within a National Nutrition Assistance Program

Many mothers are vulnerable to poor diet quality, particularly those living in low-income households. The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides nutrient-rich foods through its benefits packages, but many WIC participants are not redeeming them. We assessed the feasibility and acceptability of a digital intervention to support redemption and consumption of WIC-approved foods to ultimately improve diet quality. We enrolled 54 maternal-child dyads receiving WIC benefits to receive three to four weekly text messages for 12 weeks focused on behavioral goals to improve consumption of WIC-approved foods. We assessed engagement with weekly tracking messages and satisfaction and collected 24 h dietary recalls to assess preliminary efficacy on dietary intake. Participants were mostly non-Hispanic white (63%) and working (63%), and responded to 7.4 (standard deviation: 4.6) of the 12 weekly messages. Half (n = 27) were high engagers (responded to 80% or more of weekly messages), with 28% (n = 15) responding to all messages. Most felt the feedback (94%) and tips (87%) were helpful and would recommend the program (91%). More were consuming leafy green vegetables compared to baseline (p = 0.01). Mothers of children enrolled in WIC found a text messaging intervention focused on consumption of WIC-approved foods enjoyable and helpful.

Support for healthy breastfeeding mothers with healthy term babies

BACKGROUND

There is extensive evidence of important health risks for infants and mothers related to not breastfeeding. In 2003, the World Health Organization recommended that infants be breastfed exclusively until six months of age, with breastfeeding continuing as an important part of the infant's diet until at least two years of age. However, current breastfeeding rates in many countries do not reflect this recommendation.

OBJECTIVES

1. To describe types of breastfeeding support for healthy breastfeeding mothers with healthy term babies. 2. To examine the effectiveness of different types of breastfeeding support interventions in terms of whether they offered only breastfeeding support or breastfeeding support in combination with a wider maternal and child health intervention ('breastfeeding plus' support).  3. To examine the effectiveness of the following intervention characteristics on breastfeeding support:      a. type of support (e.g. face-to-face, telephone, digital technologies, group or individual support, proactive or reactive);      b. intensity of support (i.e. number of postnatal contacts);      c. person delivering the intervention (e.g. healthcare professional, lay person);     d. to examine whether the impact of support varied between high- and low-and middle-income countries.

SEARCH METHODS

We searched Cochrane Pregnancy and Childbirth's Trials Register (which includes results of searches of CENTRAL, MEDLINE, Embase, CINAHL, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform (ICTRP)) (11 May 2021) and reference lists of retrieved studies.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials comparing extra support for healthy breastfeeding mothers of healthy term babies with usual maternity care. Support could be provided face-to-face, over the phone or via digital technologies. All studies had to meet the trustworthiness criteria.  DATA COLLECTION AND ANALYSIS: We used standard Cochrane Pregnancy and Childbirth methods. Two review authors independently selected trials, extracted data, and assessed risk of bias and study trustworthiness.  The certainty of the evidence was assessed using the GRADE approach.

MAIN RESULTS

This updated review includes 116 trials of which 103 contribute data to the analyses. In total more than 98,816 mother-infant pairs were included.  Moderate-certainty evidence indicated that 'breastfeeding only' support probably reduced the number of women stopping breastfeeding for all primary outcomes: stopping any breastfeeding at six months (Risk Ratio (RR) 0.93, 95% Confidence Interval (CI) 0.89 to 0.97); stopping exclusive breastfeeding at six months (RR 0.90, 95% CI 0.88 to 0.93); stopping any breastfeeding at 4-6 weeks (RR 0.88, 95% CI 0.79 to 0.97); and stopping exclusive breastfeeding at 4-6 (RR 0.83 95% CI 0.76 to 0.90). Similar findings were reported for the secondary breastfeeding outcomes except for any breastfeeding at two months and 12 months when the evidence was uncertain if 'breastfeeding only' support helped reduce the number of women stopping breastfeeding.  The evidence for 'breastfeeding plus' was less consistent. For primary outcomes there was some evidence that 'breastfeeding plus' support probably reduced the number of women stopping any breastfeeding (RR 0.94, 95% CI 0.91 to 0.97, moderate-certainty evidence) or exclusive breastfeeding at six months (RR 0.79, 95% CI 0.70 to 0.90).  'Breastfeeding plus' interventions may have a beneficial effect on reducing the number of women stopping exclusive breastfeeding at 4-6 weeks, but the evidence is very uncertain (RR 0.73, 95% CI 0.57 to 0.95). The evidence suggests that 'breastfeeding plus' support probably results in little to no difference in the number of women stopping any breastfeeding at 4-6 weeks (RR 0.94, 95% CI 0.82 to 1.08, moderate-certainty evidence). For the secondary outcomes, it was uncertain if 'breastfeeding plus' support helped reduce the number of women stopping any or exclusive breastfeeding at any time points.  There were no consistent findings emerging from the narrative synthesis of the non-breastfeeding outcomes (maternal satisfaction with care, maternal satisfaction with feeding method, infant morbidity, and maternal mental health), except for a possible reduction of diarrhoea in intervention infants.  We considered the overall risk of bias of trials included in the review was mixed. Blinding of participants and personnel is not feasible in such interventions and as studies utilised self-report breastfeeding data, there is also a risk of bias in outcome assessment.   We conducted meta-regression to explore substantial heterogeneity for the primary outcomes using the following categories: person providing care; mode of delivery; intensity of support; and income status of country.  It is possible that moderate levels (defined as 4-8 visits) of 'breastfeeding only' support may be associated with a more beneficial effect on exclusive breastfeeding at 4-6 weeks and six months. 'Breastfeeding only' support may also be more effective in reducing women in low- and middle-income countries (LMICs) stopping exclusive breastfeeding at six months compared to women in high-income countries (HICs). However, no other differential effects were found and thus heterogeneity remains largely unexplained. The meta-regression suggested that there were no differential effects regarding person providing support or mode of delivery, however, power was limited.  AUTHORS' CONCLUSIONS: When 'breastfeeding only' support is offered to women, the duration and in particular, the exclusivity of breastfeeding is likely to be increased. Support may also be more effective in reducing the number of women stopping breastfeeding at three to four months compared to later time points.  For 'breastfeeding plus' interventions the evidence is less certain. Support may be offered either by professional or lay/peer supporters, or a combination of both. Support can also be offered face-to-face, via telephone or digital technologies, or a combination and may be more effective when delivered on a schedule of four to eight visits. Further work is needed to identify components of the effective interventions and to deliver interventions on a larger scale.

How do Central American Parents in the United States View the Importance of and Obtain Information About Behaviors Associated with the Risk of Early Childhood Obesity?

Background: Data suggest that Latinx preschool-age children are at increased risk of obesity. The fastest-growing Latinx population in the United States originates from El Salvador, Guatemala, and Honduras, also known as the Northern Triangle countries. Purpose: To describe how Central American parents from the Northern Triangle countries perceive the importance of energy balance-related behaviors (EBRBs), their preferred sources to obtain information about EBRBs, and to assess whether these differ by parent's gender and country of the nativity. Methods: Cross-sectional survey. Results: Seventy-four parents with at least one child between 2 and 5 years of age participated in the study. More than half were immigrants from El Salvador, Guatemala, and Honduras and were classified as having low acculturation. Mothers perceived consuming >5 fruits and vegetables daily, limiting sugar-sweetened beverages consumption, and having <2 hours daily screen time as extremely important, whereas fathers perceived these behaviors as being less important. Although a higher proportion of foreign-born than US-born parents perceived most of the assessed EBRBs (4 out of 6) as extremely important, these differences were not significant. Parents reported multiple sources to obtain EBRB-related information. Direct person-to-person interactions were the most commonly preferred sources, with pediatricians being the top source (97.3%), followed by other parents (86.5%), and WIC professionals (74.3%). Pediatricians were the preferred source to obtain information about EBRBs, irrespective of parent's gender and country of the nativity. A higher proportion of US-born than foreign-born parents reported a preference to obtain EBRB-related information from other parents. Conclusions: Findings suggest the significance of understanding how Central American parents perceive the importance of EBRBs and the sources they would prefer to obtain information for their children's EBRBs. Study findings have implications for health education and obesity prevention interventions designed to reach and deliver key evidence-based child health information to Central American parents from the Northern Triangle countries in the United States.

Decídetexto: Feasibility and Acceptability of a Mobile Smoking Cessation Intervention in Puerto Rico

The purpose of this pilot study was to assess the feasibility and acceptability of a mobile smoking cessation intervention in Puerto Rico. This was a single-arm pilot study with 26 smokers in Puerto Rico who were enrolled in Decídetexto, a mobile smoking cessation intervention. Decídetexto incorporates three integrated components: (1) a tablet-based software that collects smoking-related information to develop an individualized quit plan, (2) a 24-week text messaging counseling program with interactive capabilities, and (3) pharmacotherapy support. Outcome measures included self-reported 7-day point prevalence abstinence at Months 3 and 6, pharmacotherapy adherence, satisfaction with the intervention, and changes in self-efficacy. The average age of the participants was 46.8 years (SD 12.7), half of them (53.8%) were female. Most participants (92.3%) smoked daily and half of them (53.8%) used menthol cigarettes. All participants requested nicotine patches at baseline. However, only 13.0% of participants used the patch >75% of days. At Month 3, 10 participants (38.4%) self-reported 7-day point prevalence abstinence (88.5% follow-up rate). At Month 6, 16 participants (61.5%) self-reported 7-day point prevalence abstinence (76.9% follow-up rate). Most participants (90%, 18/20) reported being satisfied/extremely satisfied with the intervention at Month 6. Self-efficacy mean scores significantly increased from 40.4 (SD 12.1) at baseline to 57.9 (SD 11.3) at Month 3 (p < 0.01). The study suggests that Decídetexto holds promise for further testing among Puerto Rican smokers.

Process evaluations of early childhood obesity prevention interventions delivered via telephone or text messages: a systematic review

Background

Increasingly, public health interventions are delivered via telephone and/or text messages. Recent systematic reviews of early childhood obesity prevention interventions have not adequately reported on the way interventions are delivered and the experiences/perceptions of stakeholders. We aimed to summarise the literature in early childhood obesity prevention interventions delivered via telephone or text messages for evidence of application of process evaluation primarily to evaluate stakeholders’ acceptability of interventions.

Methods

A systematic search of major electronic databases was carried out using the Population, Intervention, Comparison, Outcomes framework. Studies were included if interventions were delivered via telephone/text messages; aimed at changing caregivers’ behaviours to prevent early childhood obesity; with one or more outcomes related to early obesity risk factors such as breastfeeding, solid feeding, tummy time, sleep and settling, physical activity and screen time; published from inception to May 2020. All eligible studies were independently assessed by two reviewers using the Cochrane Collaboration tool for assessing risk of bias. Qualitative studies were assessed using the Consolidated Criteria for Reporting Qualitative Research and Standards for Reporting Qualitative Research tools.

Results

Twenty-four studies were eligible, and the overall risk of bias was low. Eight studies (33%) had evidence of process evaluation that examined participants’ perceptions of interventions. Participants appreciated the convenience of receiving interventions via telephone or text messages. 63% of all studies in this review showed improvement in one or more behaviours related to childhood obesity prevention. Participants were likely to modify behaviours if they received information from a credible source such as from health professionals.

Conclusion

There is limited reporting of stakeholders’ experiences in early obesity prevention studies delivered by telephone or text messages. Only one-third of studies examined participants’ acceptability and the potential for delivery of childhood obesity prevention interventions conveniently using this mode of delivery. Interventions delivered remotely via telephone or text messages have the potential to reach equal or a greater number of participants than those delivered via face-to-face methods. Future research should build in process evaluation alongside effectiveness measurements to provide important insight into intervention reach, acceptability and to inform scale up.

Education of family members to support weaning to solids and nutrition in later infancy in term-born infants

BACKGROUND

Education of family members about infant weaning practices could affect nutrition, growth, and development of children in different settings across the world.

OBJECTIVES

To compare effects of family nutrition educational interventions for infant weaning with conventional management on growth and neurodevelopment in childhood.

SEARCH METHODS

We used the standard strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 5), MEDLINE via PubMed (1966 to 26 June 2018), Embase (1980 to 26 June 2018), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to 26 June 2018). We searched clinical trials databases, conference proceedings, and references of retrieved articles. We ran an updated search from 1 January 2018 to 12 December 2019 in the following databases: CENTRAL via CRS Web, MEDLINE via Ovid, and CINAHL via EBSCOhost.

SELECTION CRITERIA

We included randomised controlled trials that examined effects of nutrition education for weaning practices delivered to families of infants born at term compared to conventional management (standard care in the population) up to one year of age.

DATA COLLECTION AND ANALYSIS

Two review authors independently identified eligible trial reports from the literature search and performed data extraction and quality assessments for each included trial. We synthesised effect estimates using risk ratios (RRs), risk differences (RDs), and mean differences (MDs), with 95% confidence intervals (CIs). We used the GRADE approach to assess the certainty of evidence.

MAIN RESULTS

We included 21 trials, recruiting 14,241 infants. Five of the trials were conducted in high-income countries and the remaining 16 were conducted in middle- and low-income countries. Meta-analysis showed that nutrition education targeted at improving weaning-related feeding practices probably increases both weight-for-age z scores (WAZ) (MD 0.15 standard deviations, 95% CI 0.07 to 0.22; 6 studies; 2551 infants; I² = 32%; moderate-certainty evidence) and height-for-age z scores (0.12 standard deviations, 95% CI 0.05 to 0.19; 7 studies; 3620 infants; I² = 49%; moderate-certainty evidence) by 12 months of age. Meta-analysis of outcomes at 18 months of age was heterogeneous and inconsistent in the magnitude of effects of nutrition education on WAZ and weight-for-height z score across studies. One trial that assessed effects of nutrition education on growth at six years reported an uncertain effect on change in height and body mass index z score. Two studies investigated effects of nutrition education on neurodevelopment at 12 to 24 months of age with conflicting results. No trials assessed effects of nutrition education on long-term neurodevelopmental outcomes.

AUTHORS' CONCLUSIONS

Nutrition education for families of infants may reduce the risk of undernutrition in term-born infants (evidence of low to moderate certainty due to limitations in study design and substantial heterogeneity of included studies). Modest effects on growth during infancy may not be of clinical significance. However, it is unclear whether these small improvements in growth parameters in the first two years of life affect long-term childhood growth and development. Further studies are needed to resolve this question.
