Who's holding the baby? A prospective diary study of the contact patterns of mothers with an infant.

ABSTRACT:

Background

Models of infectious disease are increasingly utilising empirical contact data to quantify the number of potentially infectious contacts between age groups. While a growing body of data is being collected on contact patterns across many populations, less attention has been paid to the social contacts of young infants. We collected information on the social contacts of primary carers of young infants and investigated their potential for use as a proxy for contacts made by their infant.

Methods

We recruited primary carers of infants under one year of age residing in two geographically, demographically and socioeconomically distinct local government areas of Melbourne, Australia - Boroondara and Hume - including a sub-group of Turkish-speaking participants. Participants recorded their own contacts in a paper diary and noted whether their infant was present or absent. Information collected included times at an address; description of location; and details on people contacted at the location. Descriptive summary measures and distributions of contacts by location type, intensity, day of contact and by age are reported.

Results

Of the 226 participants recruited, 220 completed diaries were returned. Participant contact patterns were similar across all groups, with respect to the types of locations, intensity and day of contact, with some variation in the number of unique daily contacts. The infant was present at around 85% of locations at which the primary carer contacted other individuals. The majority of contacts occurring when the infant was present were in Own Home (32%), Retail and Hospitality (18%) and Transport (18%) settings. The mean daily number of unique contacts by infants was estimated as 9.1, 8.7 and 6.5 in Boroondara, Hume (English) and Hume (Turkish), respectively, with a similar age distribution across each of our surveyed groups.

Conclusions

Our demonstration that contact patterns of mothers with infants are reasonably robust to socioeconomic and cultural differences is a step forward in modelling infectious disease transmission. With infants spending most of their time in the company of their mother, contact patterns of mothers are a useful proxy measure of infant contact patterns. The age distribution of contacts made by infants estimated in this study may be used to supplement population-wide contact information commonly used in infectious disease transmission models.

Project description:INTRODUCTION:Universal access to quality early childhood development and care is a fundamental part of Sustainable Development Goal 4.2.1. Research from diverse settings, including that in low and middle income countries, now demonstrates the positive impact that interventions to promote play, stimulation, early communication and responsiveness can have, not just on child development, but on long term gains in education and economic growth. International agencies have recently produced the Nurturing Care Framework for Early Child Development in order to promote this and to encourage countries to move the focus from child survival to child thrival. Research on the best methods of integration of these programmes into present care practices, particularly in African settings is still very limited. METHODS:We used qualitative methods to gain an understanding of care practices (play, developmental stimulation, early communication and responsive feeding) for children 0-2 years. We conducted 18 focus groups (FGDs), six PFGDs (Participatory Research focus groups), 18 in depth interviews (IDIs) and 20 observations with caregivers in rural and urban settings of Malawi. We used a topic guide, audio-recorded the FGDs and IDIS and transcribed them in Chichewa or Yao and then into English. We coded data using an inductive approach to thematic analysis. We placed the data within a framework with the emerging major and minor themes. We conducted quality assurance for translations and coding frameworks through cross comparison of data and used respondent validation to check our results. RESULTS:Malawian caregivers see children's play as a consequence of good health and wellbeing, less an interaction that a parent undertakes to promote wellbeing and learning. Non-verbal communication and responsiveness with infants is clearly present and caregivers have many one-on-one interactions with young infants. Furthermore, many caregivers have good knowledge of feeding recommendations but cannot always follow these due to constraints on money. When children become mobile (toddlers), play is an activity done more often between children or with other caregivers such as siblings or grandparents. Community members consider that caring for children from 0-2 years is a woman's domain. Despite this, both men and women acknowledge the importance of maternal wellbeing in enabling good care of children. The present socioeconomic situation of most families in our study means that income generation and food security come first. Many mothers spend most of their time managing the responsibilities of daily living and have limited time to dedicate to children's play, responsiveness and communication with their children. DISCUSSION:Programmes promoted as part of the Nurturing Care Framework which provide advice on developmental stimulation, play, early communication and responsive feeding should ensure that topics within these programmes are culturally appropriate for the setting. Furthermore, programmes must not be an added burden to parents but be supportive to parents managing many responsibilities of daily living. Multi-sectorial approaches where both men and women are provided with knowledge but are also supported through programmes which address family finances, safe spaces for children whilst families are working, and family mental health and relationships may enable programmes to work more effectively.

Project description:Understanding animal movements is an important factor for the development of meaningful surveillance and control programs, but also for the development of disease spread models. We analysed the Danish pig movement network using static and temporal network analysis tools to provide deeper insight in the connection between holdings dealing with pigs, such as breeding and multiplier herds, production herds, slaughterhouses or traders. Pig movements, which occurred between 1st January 2006 and 31st December 2015 in Denmark, were summarized to investigate temporal trends such as the number of active holdings, the number of registered movements and the number of pigs moved. To identify holdings and holding types with potentially higher risk for introduction or spread of diseases via pig movements, we determined loyalty patterns, annual network components and contact chains for the 24 registered holding types. The total number of active holdings as well as the number of pig movements decreased during the study period while the holding sizes increased. Around 60-90% of connections between two pig holdings were present in two consecutive years and around one third of the connections persisted within the considered time period. Weaner herds showed the highest level of in-loyalty, whereas we observed an intermediate level of in-loyalty for all breeding sites and for production herds. Boar stations, production herds and trade herds showed a high level of out-loyalty. Production herds constituted the highest proportion of holdings in the largest strongly connected component. All production sites showed low levels of in-going contact chains and we observed a high level of out-going contact chain for breeding and multiplier herds. Except for livestock auctions, all transit sites also showed low levels of out-going contact chains. Our results reflect the pyramidal structure of the underlying network. Based on the considered disease, the time frame for the calculation of network measurements needs to be adapted. Using these adapted values for loyalty and contact chains might help to identify holdings with high potential of spreading diseases and thus limit the outbreak size or support control or eradication of the considered pathogen.

Project description:BackgroundThere is a strong evidence base for the benefits of parenting interventions for parents without severe mental illness (SMI). As the impact of maternal SMI can be significant on child development, mothers need support to maximise outcomes for themselves and their children. Some mothers with SMI require admission jointly with their baby to a Mother and Baby Unit (MBU), a psychiatric inpatient ward, for assessment and treatment. However, MBUs do not yet offer formally evaluated, evidence-based parenting interventions as a matter of routine. This paper describes a study to investigate the feasibility and acceptability of conducting a randomised controlled trial (RCT) to evaluate a parenting and psychological intervention targeting the mother's and infant's wellbeing for mothers admitted to a MBU.Methods/designThis study is a multisite, single-blind feasibility trial with half the participants randomised to the Baby Triple P Positive Parenting Programme plus treatment as usual (TAU) and the other half randomised to TAU alone. Self-report and observer-rated assessments are collected at baseline, 10 weeks post-baseline and 6 months post-baseline. Participants are mothers admitted to a MBU in the Northwest of England or the Midlands. Participants are included if they are fluent in English to provide informed, written consent. Our objective is to determine whether we can recruit 66 women, randomise 60, and retain them in the intervention and study, and whether the intervention and study procedures are acceptable. As part of a nested process evaluation, qualitative interview data from trial participants and MBU staff will inform feasibility and acceptability. The feasibility of collecting data required to conduct an economic evaluation of the intervention will also be explored.DiscussionAlthough research has been conducted in relation to mothers with severe mental illness and MBUs, to our knowledge, this is the first controlled trial to test the feasibility, acceptability, uptake and retention alongside the potential efficacy of a parenting intervention for this population. This study is essential to examine the contextual challenges involved in this setting with this population and to identify any refinements required.Trial registrationISRCTN12765736 .

Project description:BackgroundThe complementary feeding period is a time of unparalleled dietary change for every human, during which the diet changes from one that is 100% milk to one that resembles the usual diet of the wider family in less than a year. Despite this major dietary shift, we know relatively little about food and nutrient intake in infants worldwide and virtually nothing about the impact of baby food "pouches" and "baby-led weaning" (BLW), which are infant feeding approaches that are becoming increasingly popular. Pouches are squeezable containers with a plastic spout that have great appeal for parents, as evidenced by their extraordinary market share worldwide. BLW is an alternative approach to introducing solids that promotes infant self-feeding of whole foods rather than being fed purées, and is popular and widely advocated on social media. The nutritional and health impacts of these novel methods of infant feeding have not yet been determined.ObjectiveThe aim of the First Foods New Zealand study is to determine the iron status, growth, food and nutrient intakes, breast milk intake, eating and feeding behaviors, dental health, oral motor skills, and choking risk of New Zealand infants in general and those who are using pouches or BLW compared with those who are not.MethodsDietary intake (two 24-hour recalls supplemented with food photographs), iron status (hemoglobin, plasma ferritin, and soluble transferrin receptor), weight status (BMI), food pouch use and extent of BLW (questionnaire), breast milk intake (deuterium oxide "dose-to-mother" technique), eating and feeding behaviors (questionnaires and video recording of an evening meal), dental health (photographs of upper and lower teeth for counting of caries and developmental defects of enamel), oral motor skills (questionnaires), and choking risk (questionnaire) will be assessed in 625 infants aged 7.0 to 9.9 months. Propensity score matching will be used to address bias caused by differences in demographics between groups so that the results more closely represent a potential causal effect.ResultsThis observational study has full ethical approval from the Health and Disability Ethics Committees New Zealand (19/STH/151) and was funded in May 2019 by the Health Research Council (HRC) of New Zealand (grant 19/172). Data collection commenced in July 2020, and the first results are expected to be submitted for publication in 2022.ConclusionsThis large study will provide much needed data on the implications for nutritional intake and health with the use of baby food pouches and BLW in infancy.Trial registrationAustralian New Zealand Clinical Trials Registry ACTRN12620000459921; http://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=379436.International registered report identifier (irrid)DERR1-10.2196/29048.
