Does IPV Boost Intestinal Immunity among Children under Five Years of Age? An Experience from Pakistan.

The oral poliovirus vaccine (OPV) has been the mainstay of polio eradication, especially in low-income countries, and its use has eliminated wild poliovirus type 2. However, the inactivated poliovirus vaccine (IPV) is safer than OPV, as IPV protects against paralytic poliomyelitis without producing adverse reactions. The present study compared mucosal and humoral responses to poliovirus vaccines administered to previously OPV-immunized children to assess the immunity gap in children in areas of high poliovirus transmission. A cluster-randomized trial was implemented in three high-risk districts of Pakistan-Karachi, Kashmore, and Bajaur-from June 2013 to May 2014. This trial was community-oriented and included three arms, focusing on healthy children below five years of age. The study involved the randomization of 387 clusters, of which 360 were included in the final analysis. The control arm (A) received the routine polio program bivalent poliovirus vaccine (bOPV). The second arm (B) received additional interventions, including health camps providing routine vaccinations and preventive maternal and child health services. In addition to the interventions in arm B, the third arm (C) was also provided with IPV. Blood and stool samples were gathered from children to evaluate humoral and intestinal immunity. The highest levels of poliovirus type 1 serum antibodies were observed in Group C (IPV + OPV). The titers for poliovirus type 2 (P2) and poliovirus type 3 (P3) were noticeably higher in those who had received a routine OPV dose than in those who had not across all study groups and visits. Providing an IPV booster after at least two OPV doses could potentially fill immunity gaps in regions where OPV does not show high efficacy. However, IPV only marginally enhances humoral immunity and fails to offer intestinal immunity, which is critical to stop the infection and spread of live poliovirus in populations that have not been exposed before.

Sustainable preventive integrated child health care: reflections on the importance of multidisciplinary and multisectoral stakeholder engagement

ABSTRACT Worldwide, 85% of all children who die are under the age of five. A recent scoping review examining the literature from 2000 to 2021 shows the importance of sustainable integrated preventive child health care for improving child health, enhancing the uptake of preventive child health services, and decreasing health-care costs. In 2022, we organised a stakeholder workshop in Uganda to discuss and contextualise the findings of the scoping review. The workshop took place under the umbrella of the Centre of Excellence for Sustainable Health, a virtual collaborative centre co-hosted by Makerere University in Uganda and Karolinska Institutet in Sweden. The workshop convened multidisciplinary and multisectoral stakeholders, including parents, nurses, paediatricians, nutritionists, village health team members, religious leaders, social workers, teachers, lawyers, health and climate researchers, and representatives from the police, the agricultural sector, the Ministry of Health, the World Health Organization, and other international and national non-governmental organisations, among others. We reflect on the importance of multidisciplinary and multisectoral stakeholder engagement, not only in building bridges between research and practice but also in linking sectors and connecting people for sustainable preventive integrated child health care. Though an important step, this workshop was only a first step; over time, relationships must be nurtured, multisectoral systems built and research and policy closely connected. We hope this workshop will not remain a one-off event but becomes an institutionalised effort that sparks action for sustainable preventive integrated child health care in Kampala and beyond, and sustainable health for all.

Health postservice readiness and use of preventive and curative services for suspected childhood pneumonia in Ethiopia: a cross-sectional study

ObjectivePneumonia is the single-leading cause of infectious disease deaths in children under-5. Despite this challenge, the utilisation of preventive and curative child health services remains low in Ethiopia. We investigated...

Impact of state-level training requirements for medical providers on receipt of preventive oral health services for young children enrolled in Medicaid.

Young children enrolled in Medicaid make few dental visits and have high rates of tooth decay. To improve access to care, state Medicaid programs have enacted policies encouraging nondental providers to deliver preventive oral health services (POHS) in medical offices. Policies vary by state, with some states requiring medical providers to obtain training prior to delivering POHS. Our objective was to test whether these training requirements were associated with higher rates of POHS for Medicaid-enrolled children <6 years. This study took advantage of a natural experiment in which policy enactment occurred across states at different times. We used Medicaid Analytic eXtract enrollment and claims data, public policy data, and Area Health Resource Files data. We examined an unweighted sample of 8,711,192 (45,107,240 weighted) Medicaid-enrolled children <6 years in 38 states from 2006 to 2014. Multivariable logistic regression models estimated the odds a child received POHS in a calendar year. Results are presented as adjusted probabilities. Five or more years after policy enactment, the probability of a child receiving POHS in medical offices was 10.7percent in states with training requirements compared to 5.0percent in states without training requirements (P=0.01). Findings were similar when receipt of any POHS in medical or dental offices was examined 5 or more years post-policy-enactment (requirement=42.5percent, no requirement=33.6percent, P < 0.001). Medicaid policies increased young children's receipt of POHS and at higher rates in states that required POHS training. These results suggest that oral health training for nondental practitioners is a key component of policy success.

Coverage assessment of maternal and child health services provided at Urban Health and Nutrition Day in urban slums of Jamnagar Municipal Corporation area

Introduction: Urban Health and Nutrition Day (UHND) is an initiative to provide preventive, promotive, and curative maternal and child health services monthly on fixed day. It is mainly designed to reach out to those who are living in urban slums and for serving vulnerable. The study was conducted to assess the utilization of services provided to mother and child at Mamta session.Materials and Methods: A cross-sectional study was conducted in urban slums of Jamnagar. In the first stage, 30 Anganwadi centers were chosen by systematic random sampling, and in the second stage, 8 postnatal women with 8 children were included.Results: Out of 240 participants, 80% of women registered their pregnancy at Mamta session and 86% were having Mother and Child Protection Card at the time of visit. Basic health checkups containing blood pressure and weight were measured for around 90%, three-fourth of women were checked for hemoglobin % and urine for albumin, and only 29% were done with abdominal examination. Health education component was found to be much-sidelined portion of UHND session in both mother and child care in this study. From surveyed children, 81.6% were registered at session site; from those registered, 62% attend the session regularly; 80% of children were weighed; only 12% of children's weight was recorded in Mamta card; and 50% of mothers were explained about weight and its interpretation. Fifty-four percent of women had given colostrum to their babies, and the same proportion of mother gave prelacteal feed to their children.Conclusion: There is a need to sensitize health workers about the importance of giving health education to mothers which is found to be the most poorly executed component of the study.

Effects of the Dental Preventive Health Services for Children on Oral Health-Related Quality of Life

The purpose of this study was to investigate the effects of public preventive dental healthcare services named the “Dental Preventive Health Services for Children” (DPHSC) on oral health-related quality of life (OHRQoL) in Korean children. Of the total 20,802 beneficiaries in 2018, 110 10-year-old elementary school students were randomly selected and were requested to complete a survey using the Korean version of Child Oral Health Impact Profile (COHIP) questionnaire before and after participating in DPHSC. Overall, 107 participants completed the pre- and post-survey. COHIP scores and clinical results such as numbers of decayed and missing teeth, malocclusion, and oral hygiene status from dental examination were statistically analyzed and the reliability and the validity of the responses were verified. There was a significant clinical increase in mean overall COHIP scores following DPHSC (&lt;i&gt;p&lt;/i&gt; &lt; 0.001, effect size 1.05). Children with decayed and missing teeth demonstrated poor OHRQoL. In conclusion, DPHSC can improve the OHRQoL of 10-year-old children.

Agile Application of Digital Health Interventions during the COVID-19 Refugee Response.

The intersection of digital health platforms and refugee health in the context of the novel 2019 coronavirus disease (COVID-19) has not yet been explored. We discuss the ability of a novel mobile health (mhealth) platform to be effectively adapted to improve health access for vulnerable displaced populations. In a preliminary analysis of 200 Syrian refugee women, we found positive user feedback and uptake of an mhealth application to increase access to preventive maternal and child health services for Syrian refugees under temporary protection in Turkey. Rapid adaptation of this application was successfully implemented during a global pandemic state to perform symptomatic assessment, disseminate health education, and bolster national prevention efforts. We propose that mhealth interventions can provide an innovative, cost-effective, and user-friendly approach to access the dynamic needs of refugees and other displaced populations, particularly during an emerging infectious disease outbreak.

Recommendations for Preventive Pediatric Health Care

The objective of this study was to compare the receipt of preventive health services for children with and without special health care needs and to identify predictors of these health services for children with special health care needs using nationally representative data. Data from the 2002 and 2003 Medical Expenditure Panel Surveys were analyzed. A total of 18 279 children aged 3 to 17 years were included in our study. The Child Preventive Health Supplement was used to identify caregiver recall of specific health screening measures and anticipatory guidance during the previous 12 months. Odds ratios were calculated for predictive factors of preventive services for children with special health care needs.

Impact of a Medicaid policy on preventive oral health services for children with intellectual disabilities, developmental disabilities, or both

BackgroundIntegrating preventive oral health services (POHS) into medical offices may ease access to care for children with intellectual and developmental disabilities (IDD). The authors examined the impact of state policies allowing delivery of POHS in medical offices on receipt of POHS among Medicaid enrollees with IDD. MethodsThe authors used 2006 through 2014 Medicaid data for children with IDD aged 6 months through 5 years from 38 states. IDD were defined using 14 condition codes from Centers for Medicare & Medicaid Services Chronic Conditions Data Warehouse. The length of the state’s medical POHS policy (no policy, < 1 year, 1 year, 2 years, 3 years, or ≥ 4 years) was interacted with an indicator that the child was younger than 3 years. The authors used logistic regression models to estimate the likelihood that a child received POHS in a medical office or in a medical or dental office in a given year. ResultsAmong 447,918 children with IDD, 1.6% received POHS in medical offices. Children younger than 3 years in states with longer-enacted policies had higher rates of receiving POHS. For example, the predicted probability of receiving POHS was 40.6% (95% confidence interval, 36.3% to 44.9%) for children younger than 3 years in states with a medical POHS policy for more than 4 years compared with 30.6% (95% confidence interval, 27.8% to 33.5%) for children in states without a policy. ConclusionsState Medicaid policies allowing delivery of POHS in medical offices increased receipt of POHS among Medicaid-enrolled children with IDD who were younger than 3 years. Practical ImplicationsFew children with IDD receive POHS in any setting. Efforts are needed to reduce barriers to POHS for publicly insured children with IDD.

Wealth-based equity in maternal, neonatal, and child health services utilization: a cross-sectional study from Ethiopia

BackgroundDespite the pro-poor health policies in Ethiopia, the utilization of maternal, neonatal, and child health services remains a challenge for the country. Health equity became central in the post-2015 Sustainable Development Goals globally and is a priority for Ethiopia. The aim of this study was to assess equity in utilization of a range of maternal and child health services by applying absolute and relative equity indices.MethodsData on maternal and child health utilization emanated from a baseline survey conducted for a large project ‘Optimizing the Health Extension Program from December 2016 to February 2017 in four regions of Ethiopia. The utilization of four or more antenatal care visits; skilled birth attendance; postnatal care within 2 days after childbirth; immunization with BCG, polio 3, pentavalent 3, measles and full immunization of children aged 12–23 months; and vitamin A supplementation for 6–23 months old children were stratified by wealth quintiles. The socioeconomic status of the household was assessed by household assets and measured by constructing a wealth index using principal component analysis. Equity was assessed by applying two absolute inequity indices (Wealth index [quintile 5- quintile 1] and slope index of inequality) and two relative inequity indices (Wealth index [quintile5: quintile1] and concentration index).ResultsThe maternal health services utilization was low and inequitably distributed favoring the better-off women. About 44, 71, and 18% of women from the better-off households had four or more antenatal visits, utilized skilled birth attendance and postnatal care within two days compared to 20, 29, and 8% of women from the poorest households, respectively. Skilled birth attendance was the most inequitably distributed maternal health service. All basic immunizations: BCG, polio 3, pentavalent 3, measles, and full immunization in children aged 12–23 months and vitamin A supplementation were equitably distributed.ConclusionUtilization of maternal health services was low, inequitable, and skewed against women from the poorest households. In contrast, preventive child health services were equitably distributed. Efforts to increase utilization and reinforcement of pro-poor and pro-rural strategies for maternal, newborn and immunization services in Ethiopia should be strengthened.

Organisation of preventive child health services: Key to socio-economic equity in vaccine uptake?

Background: Measles has made a comeback in Western Europe, with more cases being reported each year. One factor behind this development is low vaccination coverage in socially disadvantaged segments of the population in many countries. This study investigates whether socioeconomic patterns of uptake of the measles, mumps and rubella (MMR) vaccine in the Nordic countries differ by national organisation of preventive health services for children. Methods: MMR vaccine uptake before the age of two years was analysed in register data from Denmark, Finland, Iceland and Sweden, linked to family indicators of socio-economic status (SES) from national registers. Results: Denmark, a country where child vaccinations are administered by general practitioners, presented the lowest overall coverage of MMR at 83%. It also had the greatest difference between subpopulations of low and high SES at 14 percentage points. Finland, Iceland and Sweden, countries where preschool children are vaccinated in 'well-baby' clinics, had a higher overall coverage at 91-94%, with a more equal distribution between SES groups at 1-4 percentage points. Conclusions: This study suggests that the organisation of preventive health care in special units, 'well-baby' clinics, facilitates vaccine uptake among children with low SES in a Nordic welfare context.

Determinants of continuum of care for maternal, newborn, and child health services in rural Khammouane, Lao PDR.

IntroductionThe concept of continuum of care has gained attention as measures to improve maternal, newborn, and child health. However, little is known about the factors associated with the coverage level of continuum of care in Lao PDR. Therefore, this study was conducted 1) to investigate the coverage level of continuum of care and 2) to identify barriers and promoting factors that are associated with mothers’ continuation in receiving services in rural Lao PDR.MethodsA community-based, cross sectional study was conducted in a rural district in Khammouane Province, Lao PDR, using a structured questionnaire. The outcome to the express continuum of care was assessed by the modified composite coverage index (CCI) that reflects ten maternal and child health services.ResultsIn total, 263 mothers were included in the final analyses. Only 6.8% of mothers continued to receive all MNCH services. Five factors were shown to have statistically significant associations with modified CCI score: higher educational attainment (B = 0.070, p<0.001), being a farmer (B = -0.078, p = 0.003), receiving the first antenatal care within the first trimester (B = 0.109, p<0.001), longer distance from district hospital (B = -0.012, p<0.001), and discussion with husband or family members (B = 0.057, p = 0.022).ConclusionsIn this study, we introduced the modified CCI to better explain the utilization of preventive maternal and child health services along with the continuum of care. By utilizing the modified CCI, we identified five factors as determinants of continuum of care. Furthermore, new and modifiable promoting factors were identified for continuum of care: receiving the first antenatal care within the first trimester and family and male involvement. Such demand side actions should be encouraged to improve the continuity of MNCH service use.

Preventive health services for young children in Israel: historical development and current challenges

PurposePediatric preventive health services are delivered in many different formats throughout the world. In Israel, these services for young children are provided in designated Maternal Child Health Clinics (MCHC). The history and operation of Israel’s MCHC have been described primarily in the Hebrew language medical literature with most of these reports being over a decade old. This paper provides an up to date summary of the evolution and current care in Israel’s one-hundred-year old model for the provision of preschool preventive health services. As these clinics have been recognized by the World Organization as a model for emulation, it is important that such information be made available. bodyIsrael’s MCHC provide universal care to infants and preschool children (0–6 years), free of charge. These community-based clinics provide developmental surveillance, growth monitoring, and routine childhood immunizations. Anticipatory guidance is offered to families on topics including nutrition, parenting and child safety. Screening is also performed for maternal postpartum depression and family violence. Care is given by public health nurses working in collaboration with physicians.The vast majority (> 96%) of the country’s children receive care in this system. Immunization coverage rates through this system are in line with World Health Organization guidelines – over 95% overall average nationally. Unfortunately, the allocated funding has not increased in proportion to the population growth. There is ongoing debate on the role of the national government in health services: should it be that of a direct services provider or focus on guidance and regulation of the health system.ConclusionMCHC well child care can help assure widespread provision of pediatric preventive health care. For this model to function, both its funding and content needs to be updated on an ongoing basis to reflect current preventive health care needs.

5.2-O6Governing healthy migrant families: migrants’ and health workers’ views and perceptions of child health and wellbeing services in the UK

Background: Migrating between countries involves adjustment and movement between healthcare systems, in addition to a changing relationship between the migrant individual/family) and the state. The objective of this paper is to explore how migrant parents and families, originating from different countries of origin (both within and outside of the EU), understand and make sense of the UK health care system, including preventive child health services. Methods: Five focus groups were held (n=28) with parents of pre-school children who had migrated from Romania, Poland, Pakistan or Somalia in the last ten years. Semi-structured interviews were also conducted with key stakeholders who were directly involved in assisting migrant parents to access UK health services, such as refugee health and link workers, an interpreter, and a health visitor. Findings: Migrant parents’ views reflected the shifting balance between state and parental responsibility, focusing on the values of a child centred society in the UK and the contrast to their country of origin. Whilst lifestyle interventions were mostly viewed positively, some migrants distrusted wider public health interventions and were critical of societal perceptions of risk. Views about acute and preventive services in the UK often reflected a more consumer-oriented value-system. Conclusion: This study highlights the relational aspects of both migrants’ and health care workers’ views about child health and wellbeing services in the context of both shifting welfare ideology in the UK and perceptions of citizenship rights

Community engagement and integrated health and polio immunisation campaigns in conflict-affected areas of Pakistan: a cluster randomised controlled trial.

SummaryBackgroundPakistan faces huge challenges in eradicating polio due to widespread poliovirus transmission and security challenges. Innovative interventions are urgently needed to strengthen community buy-in, to increase the coverage of oral polio vaccine (OPV) and other routine immunisations, and to enhance immunity through the introduction of inactivated polio vaccine (IPV) in combination with OPV. We aimed to evaluate the acceptability and effect on immunisation coverage of an integrated strategy for community engagement and maternal and child health immunisation campaigns in insecure and conflict-affected polio-endemic districts of Pakistan.MethodsWe did a community-based three-arm cluster randomised trial in healthy children aged 1 month to 5 years that resided within the study sites in three districts of Pakistan at high risk of polio. Clusters were randomly assigned by a computer algorithm using restricted randomisation in blocks of 20 by an external statistician (1:1:1) to receive routine polio programme activities (control, arm A), additional interventions with community outreach and mobilisation using an enhanced communication package and provision of short-term preventive maternal and child health services and routine immunisation (health camps), including OPV (arm B), or all interventions of arm B with additional provision of IPV delivered at the maternal and child health camps (arm C). An independent team conducted surveys at baseline, endline, and after each round of supplementary immunisation activity for acceptability and effect. The primary outcome measures for the study were coverage of OPV, IPV, and routine extended programme on immunisation vaccines and changes in the proportion of unvaccinated and fully vaccinated children. This trial is registered with ClinicalTrials.gov, number NCT01908114.FindingsBetween June 4, 2013, and May 31, 2014, 387 clusters were randomised (131 to arm A, 127 to arm B, and 129 to arm C). At baseline, 28 760 children younger than 5 years were recorded in arm A, 30 098 in arm B, and 29 126 in arm C. 359 clusters remained in the trial until the end (116 in arm A, 120 in arm B, and 123 in arm C; with 23 334 children younger than 5 years in arm A, 26 110 in arm B, and 25 745 in arm C). The estimated OPV coverage was 75% in arm A compared with 82% in arm B (difference vs arm A 6·6%; 95% CI 4·8–8·3) and 84% in arm C (8·5%, 6·8–10·1; overall p<0·0001). The mean proportion of routine vaccine doses received by children younger than 24 months of age was 43% in arm A, 52% in arm B (9%, 7–11) and 54% in arm C (11%, 9–13; overall p<0·0001). No serious adverse events requiring hospitalisation were reported after immunisation.InterpretationDespite the challenges associated with the polio end-game in high-risk, conflict-affected areas of Pakistan, a strategy of community mobilisation and targeted community-based health and immunisation camps during polio immunisation campaigns was successful in increasing vaccine coverage, including polio vaccine coverage.FundingBill & Melinda Gates Foundation.

Relationship Between Breastfeeding and Early Childhood Obesity: Results of a Prospective Longitudinal Study from Birth to 4 Years.

To study a potential link between breastfeeding in infancy and obesity at age 4. A total of 30,508 infants born during 2002-2007 from the databases of the Preventive Child Health Services in two Swedish counties and from national registers were studied. The outcome variable was obesity at age 4. Analyses were conducted by logistic regression models using the methodology of generalized estimating equations. Analyses were adjusted for child sex and maternal anthropometric and sociodemographic variables. In unadjusted analyses, any breastfeeding up to 9 months was linked to successively decreasing odds ratios (ORs) for obesity at age 4 (ORs 0.78-0.33), however, not significantly for 1 week and 2 months of breastfeeding. In adjusted analyses, the same pattern remained statistically significant for breastfeeding for 4 (OR 0.51), 6 (OR 0.55), and 9 (OR 0.47) months. Child sex, maternal education, maternal body mass index, and maternal smoking additionally influenced child obesity. Breastfeeding duration for at least 4 months may contribute independently to a reduced risk for childhood obesity at 4 years.

Mothers' Employment Attributes and Use of Preventive Child Health Services.

This study examines whether paid sick leave and hours worked per week are associated with receipt of recommended well-child visits, preventive dental care, influenza vaccines, obesity screening, and vision screening among U.S. children aged 0 to 17 years whose mothers were employed using data from the Medical Expenditure Panel Survey. Residual inclusion instrumental variables methods were used to address unobserved confounding related to maternal employment and child health care use. Instruments were the industry-specific mean of paid leave and hours worked. Fewer than half of children received the recommended number of well-child visits and dental care; only 14% of children received an influenza vaccine in the past year. Paid sick leave was associated with increased adherence to recommended well-child visits (marginal probability, 0.12; 95% confidence interval [CI] = 0.23, 0.01), preventive dental care (marginal probability, 0.28; 95% CI = 0.34, 0.33), and receipt of the influenza vaccine (marginal probability, 0.09; 95% CI = 0.13, 0.05 ).

Perceptions and Experiences of Overweight among Women in the Ga East District, Ghana.

Overweight and obesity are a growing public health challenge among women of reproductive age. While cultural norms suggest preference for an overweight body image, limited evidence exists regarding women's beliefs and experiences of overweight in Ghana. The current study explored beliefs, perceptions, experiences, and practices concerning overweight among women living in suburban Accra, Ghana. Four focus group discussions, and 10 in-depth interviews (IDI) were implemented among 42 adult women (>18 years) seeking preventive child health services in Dome, Accra. All the women in the IDI were overweight. In addition to notes, interviews and discussions were audio-recorded and transcribed for systematic content and narrative analysis. Overweight was considered undesirable by most women. Overweight individuals were often stigmatized using uncomplimentary names, such as cargo, obolo, and so on. However, some weight gain was admired and expected by women and their family and friends. Weight gain that was considered beautiful was believed to "evolve naturally." Weight gain that is either medically induced perceived as excessive was not viewed positively. Weight gain by women was perceived as a sign of financial prosperity and good care by a spouse. Overweight was perceived to be linked with heredity, childbirth, gluttony, and contraception. Adverse experiences of overweight included poor self-image, declining social lifestyle, increased disease risk, and feeling tired always. Strategies that had been used in order to lose weight included skipping meals, avoiding carbohydrate-based foods, and drinking herbal teas. There is admiration for some weight gain among women but when it is excessive, overweight is stigmatized. Misperceptions regarding partner expectations, determinants of overweight, and weight reduction strategies require effective behavior change interventions in Ghana.

Primary prevention of childhood obesity through counselling sessions at Swedish child health centres: design, methods and baseline sample characteristics of the PRIMROSE cluster-randomised trial.

BackgroundChildhood obesity is a growing concern in Sweden. Children with overweight and obesity run a high risk of becoming obese as adults, and are likely to develop comorbidities. Despite the immense demand, there is still a lack of evidence-based comprehensive prevention programmes targeting pre-school children and their families in primary health care settings. The aims are to describe the design and methodology of the PRIMROSE cluster-randomised controlled trial, assess the relative validity of a food frequency questionnaire, and describe the baseline characteristics of the eligible young children and their mothers.Methods/DesignThe PRIMROSE trial targets first-time parents and their children at Swedish child health centres (CHC) in eight counties in Sweden. Randomisation is conducted at the CHC unit level. CHC nurses employed at the participating CHC received training in carrying out the intervention alongside their provision of regular services. The intervention programme, starting when the child is 8-9 months of age and ending at age 4, is based on social cognitive theory and employs motivational interviewing. Primary outcomes are children’s body mass index and waist circumference at four years. Secondary outcomes are children’s and mothers’ eating habits (assessed by a food frequency questionnaire), and children’s and mothers’ physical activity (measured by accelerometer and a validated questionnaire), and mothers’ body mass index and waist circumference.DiscussionThe on-going population-based PRIMROSE trial, which targets childhood obesity, is embedded in the regular national (routine) preventive child health services that are available free-of-charge to all young families in Sweden. Of the participants (n = 1369), 489 intervention and 550 control mothers (75.9%) responded to the validated physical activity and food frequency questionnaire at baseline (i.e., before the first intervention session, or, for children in the control group, before they reached 10 months of age). The food frequency questionnaire showed acceptable relative validity when compared with an 8-day food diary. We are not aware of any previous RCT, concerned with the primary prevention of childhood obesity through sessions at CHC that addresses healthy eating habits and physical activity in the context of a routine child health services programme.Trial registrationISRCTN16991919
