Complementary feeding methods in the first year of life: a study protocol for a randomized clinical trial.

ABSTRACT:

Background

The traditional spoon-feeding approach to introduction of solid foods during the complementary feeding period is supported by consensus in the scientific literature. However, a method called Baby-Led Introduction to SolidS (BLISS) has been proposed as an alternative, allowing infants to self-feed with no adult interference. To date, there have been no trials in the Brazilian population to evaluate the effectiveness of BLISS in comparison to the traditional approach.

Methods/design

To evaluate and compare three different complementary feeding methods. Data on 144 mother-child pairs will be randomized into intervention groups by methods: (A) strict Parent-Led Weaning; (B) strict Baby-Led Introduction to SolidS; and (C) a mixed method. Prospective participants from Porto Alegre, Brazil, and nearby cities will be recruited through the Internet. The interventions will be performed by nutritionists and speech therapists, at 5.5 months of age of the child, at a private nutrition office equipped with a test kitchen where meals will be prepared according to the randomized method. The pairs will be followed up at 7, 9, and 12 months of age. Data will be collected through questionnaires designed especially for this study, which will include a 24h child food recall, questionnaires on the child's and parents' eating behavior, oral habits, eating difficulties, and choking prevalence. At 12 months of age, children will undergo blood collection to measure hemoglobin, ferritin, and C-reactive protein, saliva collection for analysis of genetic polymorphisms, and oral examination. Anthropometric parameters (child and maternal) will be measured at the baseline intervention, at a 9 month home visit, and at the end-of-study visit at the hospital. The primary outcome will be child growth and nutritional status z-scores at 12 months; secondary outcomes will include iron status, feeding behavior, acceptability of the methods, dietary variety, choking, eating behaviors, food preferences, acceptance of bitter and sweet flavors, suction, oral habits, oral hygiene behavior, dental caries, gingival health status, and functional constipation.

Discussion

The trial intends to ascertain whether there are potential advantages to the BLISS complementary feeding method in this specific population, generating data to support families and healthcare providers.

Project description:BackgroundInadequate and inappropriate complementary feeding are major factors contributing to excess morbidity and mortality in young children in low resource settings. Animal source foods in particular are cited as essential to achieve micronutrient requirements. The efficacy of the recommendation for regular meat consumption, however, has not been systematically evaluated.Methods/designA cluster randomized efficacy trial was designed to test the hypothesis that 12 months of daily intake of beef added as a complementary food would result in greater linear growth velocity than a micronutrient fortified equi-caloric rice-soy cereal supplement. The study is being conducted in 4 sites of the Global Network for Women's and Children's Health Research located in Guatemala, Pakistan, Democratic Republic of the Congo (DRC) and Zambia in communities with toddler stunting rates of at least 20%. Five clusters per country were randomized to each of the food arms, with 30 infants in each cluster. The daily meat or cereal supplement was delivered to the home by community coordinators, starting when the infants were 6 months of age and continuing through 18 months. All participating mothers received nutrition education messages to enhance complementary feeding practices delivered by study coordinators and through posters at the local health center. Outcome measures, obtained at 6, 9, 12, and 18 months by a separate assessment team, included anthropometry; dietary variety and diversity scores; biomarkers of iron, zinc and Vitamin B12 status (18 months); neurocognitive development (12 and 18 months); and incidence of infectious morbidity throughout the trial. The trial was supervised by a trial steering committee, and an independent data monitoring committee provided oversight for the safety and conduct of the trial.DiscussionFindings from this trial will test the efficacy of daily intake of meat commencing at age 6 months and, if beneficial, will provide a strong rationale for global efforts to enhance local supplies of meat as a complementary food for young children.Trial registrationNCT01084109.

Project description:ImportanceBreastfeeding through 6 and 12 months are 2 goals of the Centers for Disease Control and Prevention Healthy People 2020 initiative, but the 6-month goal is met for only 52% of US infants and the 12-month goal for 30% of US infants.ObjectiveTo determine whether structured, short-term formula supplementation for at-risk neonates affects the proportion still breastfeeding at 6 and 12 months.Design, setting, and participantsThis randomized clinical trial conducted at 2 US academic medical centers enrolled 164 exclusively breastfeeding mother-infant dyads of mothers who were not yet producing copious milk and infants who were 24 to 72 hours old with newborn weight loss at or above the 75th percentile for age. Participants were enrolled from January 2015 through September 2016.InterventionsEarly Limited Formula (ELF), a structured formula supplementation protocol (10 mL formula fed after each breastfeeding until mothers produced copious milk), compared with control dyads, who continued exclusive breastfeeding and received a safety teaching intervention.Main outcomes and measuresThe study's primary outcome was any breastfeeding at 6 months. Secondary outcomes included age at breastfeeding cessation and any breastfeeding at 12 months. All outcomes were assessed by maternal phone survey.ResultsEighty-two newborns were randomized to ELF and 82 to the control group. Mean (SD) maternal age was 31.4 (5.9) years, and 114 (69.5%) self-identified as non-Hispanic white; 20 (12.2%), Hispanic; 17 (10.4%), Asian; 5 (3.0%), non-Hispanic black; and 7 (4.3%), other. Compared with controls, mothers randomized to ELF were less likely to be married (n = 53 [64.6%] vs n = 66 [80.5%]; P = .03) and had shorter mean (SD) intended duration of breastfeeding (8.6 [3.4] vs 9.9 [4.4] months; P = .049). Median (interquartile range) duration of breastfeeding in the cohort was 9 (6-12) months. At 6 months, 47 (65%) infants randomized to ELF were breastfeeding, compared with 60 (77%) of the control infants (absolute difference, -12%; 95% CI, -26% to 3%; P = .12). At 12 months, 21 of the 71 ELF infants available for analysis (29.6%) were breastfeeding, compared with 37 of the available 77 (48.1%) control infants (risk difference, -18%; 95% CI, -34% to -3%). Marital status and intended breastfeeding duration were both associated with breastfeeding duration; models adjusting for these found a hazard ratio for time-to-event of breastfeeding cessation through 12 months of 0.74 (95% CI, 0.48-1.14) for ELF infants compared with infants in the control group.Conclusions and relevanceIn this cohort with high breastfeeding prevalence, ELF was not associated with any improvement in breastfeeding duration. Future research should examine the effect of ELF in populations at higher risk of early cessation.Trial registrationClinicalTrials.gov identifier: NCT02313181.

Project description:BACKGROUND:What we eat as infants and children carries long-term consequences. Apart from breastfeeding, the composition of the complementary diet, i.e. the foods given to the infant during the transition from breast milk/infant formula to regular family foods affects the child's future health. A high intake of protein, a low intake of fruits, vegetables and fish and an unfavorable distribution between polyunsaturated and saturated fats are considered to be associate with health risks, e.g. obesity, type 2 diabetes and dyslipidemia later in life. METHODS:In a randomized, controlled study from 6 to 18?months of age we will compare the currently recommended, Swedish complementary diet to one based on Nordic foods, i.e. an increased intake of fruits, berries, vegetables, tubers, whole-grain and game, and a lower intake of sweets, dairy, meat and poultry, with lower protein content (30% decrease), a higher intake of vegetable fats and fish and a systematic introduction of fruits and greens. The main outcomes are body composition (fat and fat-free mass measured with deuterium), metabolic and inflammatory biomarkers (associated with the amount of body fat) in blood and urine, gut microbiota (thought to be the link between early diet, metabolism and diseases such as obesity and insulin resistance) and blood pressure. We will also measure the participants' energy and nutrient intake, eating behavior and temperament through validated questionnaires, acceptance of new and unfamiliar foods through video-taped test meals and assessment of cognitive development, which we believe can be influenced through an increased intake of fish and milk fats, notably milk fat globule membranes (MFGM). DISCUSSION:If the results are what we expect, i.e. improved body composition and a less obesogenic, diabetogenic and inflammatory metabolism and gut microbiota composition, a more sustainable nutrient intake for future health and an increased acceptance of healthy foods, they will have a profound impact on the dietary recommendations to infants in Sweden and elsewhere, their eating habits later in life and subsequently their long-term health.

Project description:ImportanceBaby-led approaches to complementary feeding, which promote self-feeding of all nonliquid foods are proposed to improve energy self-regulation and lower obesity risk. However, to date, no randomized clinical trials have studied this proposition.ObjectiveTo determine whether a baby-led approach to complementary feeding results in a lower body mass index (BMI) than traditional spoon-feeding.Design, setting, and participantsThe 2-year Baby-Led Introduction to Solids (BLISS) randomized clinical trial recruited 206 women (168 [81.6%] of European ancestry; 85 [41.3%] primiparous) in late pregnancy from December 19, 2012, through March 17, 2014, as part of a community intervention in Dunedin, New Zealand. Women were randomized to a control condition (n = 101) or the BLISS intervention (n = 105) after stratification for parity and education. All outcomes were collected by staff blinded to group randomization, and no participants withdrew because of an adverse event. Data were analyzed based on intention to treat.InterventionsMothers in the BLISS group received lactation consultant support (≥5 contacts) to extend exclusive breastfeeding and delay introduction of complementary foods until 6 months of age and 3 personalized face-to-face contacts (at 5.5, 7.0, and 9.0 months).Main outcomes and measuresThe primary outcome was BMI z score (at 12 and 24 months). Secondary outcomes included energy self-regulation and eating behaviors assessed with questionnaires at 6, 12, and 24 months and energy intake assessed with 3-day weighed diet records at 7, 12, and 24 months.ResultsAmong the 206 participants (mean [SD] age, 31.3 [5.6] years), 166 were available for analysis at 24 months (retention, 80.5%). The mean (SD) BMI z score was not significantly different at 12 months (control group, 0.20 [0.89]; BLISS group, 0.44 [1.13]; adjusted difference, 0.21; 95% CI, -0.07 to 0.48) or at 24 months (control group, 0.24 [1.01]; BLISS group, 0.39 [1.04]; adjusted difference, 0.16; 95% CI, -0.13 to 0.45). At 24 months, 5 of 78 infants (6.4%) were overweight (BMI≥95th percentile) in the control group compared with 9 of 87 (10.3%) in the BLISS group (relative risk, 1.8; 95% CI, 0.6-5.7). Lower satiety responsiveness was observed in BLISS infants at 24 months (adjusted difference, -0.24; 95% CI, -0.41 to -0.07). Parents also reported less food fussiness (adjusted difference, -0.33; 95% CI, -0.51 to -0.14) and greater enjoyment of food (adjusted difference, 0.25; 95% CI, 0.07 to 0.43) at 12 months in BLISS infants. Estimated differences in energy intake were 55 kJ (95% CI, -284 to 395 kJ) at 12 months and 143 kJ (95% CI, -241 to 526 kJ) at 24 months.Conclusions and relevanceA baby-led approach to complementary feeding did not result in more appropriate BMI than traditional spoon-feeding, although children were reported to have less food fussiness. Further research should determine whether these findings apply to individuals using unmodified baby-led weaning.Trial registrationhttp://anzctr.org.au Identifier: ACTRN12612001133820.

Project description:BackgroundEarly introduction of complementary foods has been associated with various immune disorders, oxidative stress, and obesity in childhood. The gut microbiota and the short chain fatty acids (SCFAs) they produce are postulated to be on the causal pathway. The objective of this study was to determine if early complementary feeding (i.e. consumption of solids or non-water/formula liquids at or before 3 months) is prospectively associated with infant gut microbiota composition, diversity and SCFAs at 3 and 12 months of age in the Nurture birth cohort.ResultsMother-infant dyads in the early complementary feeding group (n = 18) had similar baseline characteristics to those in the later feeding group (n = 49). We assessed differential abundance of microbial taxa (measured by 16S rRNA gene sequencing of the V4 region) by timing of complementary feeding using beta-binomial regression models (considering a two-sided FDR corrected p-value of < 0.05 as significant), and we fittted linear regression models to assess the association between early complementary feeding and SCFA concentrations (quantified using gas chromatography). After multivariable adjustment for breastfeeding, delivery method, birth weight, and gestational age, there were 13 differentially abundant microbial amplicon sequence variants (ASVs) by timing of introduction to complementary foods at 3 months and 20 ASVs at 12 months. Infants introduced to complementary foods early (vs. later) had higher concentrations of the SCFA butyric acid (mean difference = 0.65, 95% CI: 0.27, 1.04, p < 0.01) and total SCFAs (mean difference = 38.8, 95% CI: 7.83, 69.7) at 12 months. Bilophila wadsworthia and Lachnospiraceae Roseburia were associated with early (vs. later) complementary feeding and with higher butyric acid concentrations at 3 and 12 months, respectively.ConclusionsOur findings are consistent with the hypothesis that early (vs. later) introduction to complementary foods is associated with altered gut microbiota composition and butyric acid concentrations measured in stool until at least 1 year of age. Further research is needed to determine if these changes mediate future development of metabolic and immune conditions.

Project description:INTRODUCTION:Psoriasis vulgaris is a common skin disease characterized by persistent localized erythematous scaly plaques, typically on the elbows, knees, and scalp. It is an immune-abnormal disease that progresses slowly over a long period with frequent symptom recurrence. Current studies have shown that acupuncture is an effective therapy for psoriasis. However, the scientific evidence of the efficacy of auricular acupressure treatment for patients with psoriasis is still insufficient. Therefore, we designed a randomized controlled clinical trial to investigate the effect, safety, and cost-effectiveness of auricular acupressure in addition to medication in patients with psoriasis. METHODS AND ANALYSIS:This on-going study is a two-arm parallel, assessor-blinded, randomized controlled trial in which 180 participants with psoriasis will be recruited and then randomly allocated into two groups in a 1:1 ratio. Equal randomization will be conducted using a computer-generated random allocation sequence. Participants in the intervention group will receive auricular acupressure treatment once per week for 4 weeks, and calcipotriol betamethasone ointment for topical use once daily for 4 weeks. Participants in the control group will receive only calcipotriol betamethasone ointment treatment once daily for 4 weeks. All patients will be followed up for 12 weeks. The primary outcome is relapse rate. The secondary outcomes include time to relapse, rebound rate, time to new onset, Psoriasis Area and Severity Index score improvement rate, body surface area affected, a visual analogue scale, and Dermatology Life Quality Index. Cost-effectiveness analysis will be carried out from a health and community care provider perspective. DISCUSSION:This multicenter randomized controlled trial will provide important clinical evidence for the effect and safety of auricular acupressure as a complementary therapy in patients with psoriasis.

Project description:BackgroundIn Papua (Indonesia), infants with P. falciparum and/or P. vivax malaria are at risk of severe anaemia and death. We hypothesized that in an area of high malaria transmission, intermittent screening and treatment of infants with malaria (ISTi) will reduce morbidity compared to passive case detection (PCDi).MethodsWe conducted a cluster randomised, open label, superiority trial. A total of 21 clusters of village health posts (VHP) were randomised 1:1 to either IST for infants coinciding with 4 routine immunisation visits or PCDi. Healthy term infants born to consenting mothers enrolled into a maternal malaria cluster randomised trial were included in the study and followed for 12 months. Point of care malaria rapid diagnostic tests were used to detect peripheral parasitaemia at 2, 3, 4 and 9 months old in all infants in ISTi clusters and when symptomatic in PCDi clusters. Infants with detected peripheral parasitaemia were treated with dihydroartemisinin-piperaquine. The co-primary outcomes were the incidence rate of clinical malaria in the first year of life and the prevalence of parasitaemia at age 12 months. The incidence rate ratio and prevalence ratio between ISTi and PCDi were estimated using mixed-effects Poisson and log-binomial regression modelling (accounting for clustering at VHP level).ResultsBetween May 2014 and February 2017, 757 infants were enrolled into the study, 313 into 10 ISTi clusters, and 444 into 11 PCDi clusters. Overall, 132 episodes of parasitaemia were detected, of whom 17 (12.9%) were in symptomatic infants. Over 12 months, the incidence rate (IR) of clinical malaria was 24 [95% CI, 10-50] per 1000 children-years at risk in the ISTi arm and 19 [95% CI, 8,38] per 1000 children-years in the PCDi arm (adjusted incidence rate ratio [aIRR] 1.77 [95% CI, 0.62-5.01]; p = 0.280). The prevalence of parasitaemia at 12 months was 13% (33/254) in the IST clusters and 15% (57/379) in the PCD clusters (adjusted prevalence ratio (aPR) = 0.92 (95% CI, 0.70-1.21), p = 0.55). There was no difference in the risk of anaemia between treatment arms.ConclusionsIn high malaria transmission area outside of Africa, our study suggests that compared to PCDi, ISTi offers no significant benefit in reducing the risk of clinical malaria in infants born to women receiving effective protection from malaria during pregnancy.Trial registrationClinicalTrials.gov NCT02001428 , registered on 20 Nov 2013.
