Comparative effects of behaviour change techniques using eHealth and mHealth in promoting dietary behaviour: protocol for a systematic review and component network meta-analysis

What are your thoughts on this?

Introduction

Globally, it is estimated that dietary habits contribute to 22% of adult deaths and 15% of disability-adjusted life years, highlighting the critical role of dietary behaviour in public health. Despite the known benefits of healthy eating, many individuals find it challenging to change their diet for disease prevention. eHealth and mHealth interventions using behaviour change techniques (BCTs) have emerged as promising strategies to address this issue. However, the specific BCTs that are most effective in promoting dietary behaviour are not well established. This systematic review and component network meta-analysis (CNMA) aims to estimate the effect size of each BCT on fostering healthy eating.

Methods and analysis

We will include randomised controlled trials that assess the effects of eHealth and mHealth interventions on promoting changes in dietary behaviours among healthy adults. Studies with a minimum follow-up period of 3 weeks will be considered. Searches will be conducted in MEDLINE [PubMed], Embase [Dialogue], Cochrane Central Register of Controlled Trials, PsycInfo [Dialogue], ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform and the University Hospital Medical Information Network Clinical Trials Registry on 27 January 2024. Two independent reviewers will conduct title and abstract screening followed by a full-text review. Disagreements will be resolved through discussion or consultation with a third reviewer. The primary outcome is dietary behaviour, as measured by changes in the diet quality score and the intake of a specific food. Our data synthesis will apply a frequentist random-effects model for pairwise meta-analysis, network meta-analysis and an additive CNMA model to compute the effect size of each BCT. This methodological approach will reveal the positive and negative effects of each BCT and provide a ranking of these techniques, considering both direct and indirect evidence.

Ethics and dissemination

Ethical approval is not required for this systematic review because it uses existing published data. These results will be submitted for publication in a peer-reviewed journal. The current protocol was submitted to PROSPERO on 16 January 2024 (CRD 42024502217).

Caregivers perceptions of feeding practices and diet diversity among children aged 12-59 months in a rural district of South India: an analytical cross-sectional study

What are your thoughts on this?

Objective

The primary objective of this study was to assess caregivers’ perceptions of feeding practices (breastfeeding and complementary feeding) and diet diversity among children aged 12–59 months in a rural district of South India. The secondary objective was to identify potential predictors of these perceptions and diet diversity.

Design

An analytical cross-sectional study was performed from March 2023 to May 2023.

Setting

In a rural district of Tamil Nadu, South India.

Participants

This study included 301 mothers/caregivers of children between 12 and 59 months of age in a rural district of Tamil Nadu. The research gathered demographic information from caregivers, including details such as age, educational background, occupation, relationship with the child and place of residence. Additionally, the caregivers’ perspectives were evaluated through a questionnaire focused on breastfeeding/complementary feeding, and the diet diversity of the children was also assessed.

Outcome measures

The primary outcome was the perceptions of mothers/caregivers of children between 12 and 59 months of age about breastfeeding/complementary feeding practices, and the diet diversity of the children was measured. Additionally, predictors associated with these perceptions were evaluated through regression analysis.

Results

In the present study, 188 (62.5%) and 179 (59.5%) of the participants had good perceptions of breastfeeding practices and complementary feeding practices, respectively. This binomial regression revealed that subjects with unstable occupations (adjusted OR=2.24, 95% CI 1.25 to 4.01), schooling (7.71, 95% CI 2.73 to 8.9) and higher education (38.32, 95% CI 4.63 to 316.85) had increased chances of having good perceptions of breastfeeding practices. Subjects with unstable occupations (0.23, 95% CI 0.06 to 0.85), stable occupations (0.13, 95% CI 0.04 to 0.51), schooling (0.43, 95% CI 0.25 to 0.74), higher education (0.15, 95% CI 0.04 to 0.50) and increased birth weights (2.54, 95% CI 1.35 to 4.78) had increased chances of having good perceptions of complementary feeding practices (p<0.05). This study revealed that 86.4% of the children had adequate diet diversity.

Conclusion

The study revealed that most caregivers, particularly mothers, possess a strong understanding of breastfeeding and complementary feeding practices, with education and occupation exerting a notable influence. However, there is a crucial necessity to translate this knowledge into practical applications to effectively obtain feeding indicators.

Risk factors for antenatal anxiety: a cross-sectional study in field antenatal clinics in Sri Lanka

What are your thoughts on this?

Objectives

We aimed to determine the prevalence and factors affecting antenatal anxiety (AA) among Sri Lankan women.

Design

We conducted a cross-sectional analysis of first trimester data from a population-based cohort of antenatal women.

Setting

Field antenatal clinics of four field health areas in Colombo District, Sri Lanka.

Participants

Antenatal women (n=535) in the first trimester of pregnancy and aged ≥18 years were sequentially recruited when they attended antenatal clinics selected using random cluster sampling. Those with hearing difficulty, visual and speaking problems or currently on treatment for mental disorders were excluded.

Measures

We used an interviewer-administered questionnaire to collect data. The AA was identified using the validated Sinhala version of Perinatal Anxiety Screening Scale (PASS-S). Self-reported demographic and pregnancy-related information were verified against health records. Psychosocial risk factors were self-reported. We investigated the associations between potential risk factors and AA using regression models that included confounders identified through a directed acyclic graph and reported using adjusted odds ratios (ORs) with 95% confidence intervals (CIs).

Results

The prevalence of AA during the first trimester of pregnancy, identified using a PASS threshold of ≥20, was 34.4% (n=184). We found several novel risk factors for AA, namely, physical (OR 2.1; 95% CI 1.4 to 3.2) and mental health problems of self (OR 2.3; 95% CI 1.2 to 4.4), physical (OR 2.1; 95% CI 1.4 to 3.4) and mental health problems of parents/spouse (OR 6.7; 95% CI 2.8 to 16.2), traumatic life situations (OR 2.7; 95% CI 1.5 to 4.8), substance abuse by the spouse (OR 3.5; 95% CI 1.9 to 6.6) and the spouse being away (OR 2.0; 95% CI 1.1 to 3.7). The other risk factors that we identified included domestic violence among family members (OR 6.4; 95% CI 1.3 to 31.0), loss of family support (OR 2.2; 95% CI 1.0 to 5.2), financial hardships (OR 1.7; 95% CI 1.0 to 2.8), accommodation-related issues (OR 2.2; 95% CI 1.0 to 4.9), unplanned pregnancy (OR 3.7; 95% CI 1.9 to 7.3), difficulties due to pregnancy (OR 2.0; 95% CI 1.1 to 3.4), changed or stopped education (OR 2.9; 95% CI 1.7 to 5.1), recent loss of employment (OR 2.9; 95% CI 1.2 to 7.0), recent death of a loved one (OR 3.5; 95% CI 2.0 to 5.9) and sleep problems during pregnancy (OR 1.6; 95% CI 1.1 to 2.3).

Conclusions

The prevalence of antenatal anxiety is high in Sri Lanka and is associated with several risk factors, not previously described, which are potentially modifiable.

Association of regular plasmapheresis donation with serum protein and electrolyte levels: a multicentre cross-sectional study in China

What are your thoughts on this?

Background

China’s plasmapheresis donation policy differs from that of Western countries. The association between regular plasmapheresis donation and donor health in China is still unknown.

Objectives

To investigate the association of regular plasmapheresis donation with serum protein and electrolyte levels and provide scientific evidence for policy improvement.

Design

Multicentre cross-sectional study.

Setting and participants

A total of 767 regular and 726 new donors from the provinces of Sichuan, Hunan, Henan and Yunnan were recruited from September 2021 to October 2022.

Primary and secondary outcome measures

Our primary outcome focused on measuring the levels of serum protein and electrolyte levels, including total serum protein (TSP), IgG, albumin (Alb), haemoglobin (Hb), calcium, potassium (K+) and magnesium (Mg2+). The secondary outcome assessed their abnormal rates.

Results

Male and female donors in the high donation frequency group (>16 donations per year) exhibited lower IgG levels compared with new donors (p=0.008 for male donors and p=0.007 for female donors). Additionally, female donors with high donation frequency and a high total number of lifetime donations (>100 donations) had significantly lower Hb concentrations than new donors. However, no significant changes were observed in TSP, Alb, calcium, K+ and Mg2+ levels. There were also no statistically significant differences in the rates of abnormal protein and electrolyte values below the respective threshold levels between new and regular donors.

Conclusions

Plasmapheresis donation is not associated with an increased risk of abnormalities in the analysed parameters. However, the results provide preliminary evidence supporting the routine inclusion of IgG screening for donors, as plasmapheresis donation is associated with a decrease in IgG levels. Particular attention should be paid to the Hb levels of female donors, especially those who donate frequently. Testing of TSP at each donation may not be necessary.
