He's just content to sit: a qualitative study of mothers' perceptions of infant obesity and physical activity

Value of video-based education to enhance infant motor development

BACKGROUND

Parents play a vital role in promoting infant motor development and physical activity; however, there is little information available to parents on how to support healthy movement. Therefore, the purpose of this study was to assess the feasibility of implementing video-based education to improve infant physical activity and motor development.

METHODS

This multiple case study consisted of semi-structured interviews with mothers (n = 12) and early childhood experts (n = 5, e.g., pediatrician, home visitor). Participants watched pre-recorded videos and answered questions which were developed following Bowens and colleagues guide for designing feasibility studies. Data were analyzed using a directed content analysis approach.

RESULTS

Most mothers (91.7 %) reported they were highly likely to recommend the videos to others and said the best way to share these videos would be through an app or social media (83.3 %) or health care entities (e.g., hospital, pediatrician, 75 %). Half of mothers (50 %) reported they would be interested in seeing videos once a month or once every couple of months. Further, all experts agreed parents would be somewhat or highly likely to use the videos and a majority (80 %) stated they were highly likely to recommend and share videos like these. Experts' top suggestions for sharing the videos was through an app/social media (40 %) and credible websites (40 %).

DISCUSSION

Overall, the videos appear feasible for mothers. Both groups primarily suggested that videos be disseminated through social media, online, or through an app. Future research should engage parents and healthcare providers in developing videos.

Human-centered designed communication tools for obesity prevention in early life

Objective

How we communicate about obesity is critical as treatment paradigms shift upstream. We previously identified parental perceptions, concerns, beliefs, and communication preferences about early life obesity risk. We engaged parents of children 0 to 24 months of age and pediatricians from Indianapolis, Indiana, USA in the co-design of messages and tools that can be used to facilitate parent/provider conversations about early life obesity prevention.

Methods

From April to June 2021, we conducted a series of co-design workshops with parents of children ages 0 to 24 months and pediatricians to identify their preferences for communicating obesity prevention in the setting of a pediatric well visit. Human-centered design techniques, including affinity diagraming and model building, were used to inform key elements of a communication model and communication strategy messages. These elements were combined and refined to create prototype tools that were subsequently refined using stakeholder feedback.

Results

Parent participants included 11 mothers and 2 fathers: 8 white, 4 black, and 1 Asian; median age 33 years with 38% reporting annual household incomes less than $50,000. Pediatricians included 7 female and 6 male providers; 69% white. Through an iterative process of co-design, we created an exam room poster that addresses common misconceptions about infant feeding, sleep and exercise, and a behavior change plan to foster parent/provider collaboration focused on achieving children's healthy weight.

Conclusions

Our hands-on, collaborative approach may ultimately improve uptake, acceptability and usability of early life obesity interventions by ensuring that parents remain at the center of prevention efforts.

Predicting body mass index in early childhood using data from the first 1000 days

Few existing efforts to predict childhood obesity have included risk factors across the prenatal and early infancy periods, despite evidence that the first 1000 days is critical for obesity prevention. In this study, we employed machine learning techniques to understand the influence of factors in the first 1000 days on body mass index (BMI) values during childhood. We used LASSO regression to identify 13 features in addition to historical weight, height, and BMI that were relevant to childhood obesity. We then developed prediction models based on support vector regression with fivefold cross validation, estimating BMI for three time periods: 30-36 (N = 4204), 36-42 (N = 4130), and 42-48 (N = 2880) months. Our models were developed using 80% of the patients from each period. When tested on the remaining 20% of the patients, the models predicted children's BMI with high accuracy (mean average error [standard deviation] = 0.96[0.02] at 30-36 months, 0.98 [0.03] at 36-42 months, and 1.00 [0.02] at 42-48 months) and can be used to support clinical and public health efforts focused on obesity prevention in early life.

Communicating Risk for Obesity in Early Life: Engaging Parents Using Human-Centered Design Methodologies

OBJECTIVE

Pediatricians are well positioned to discuss early life obesity risk, but optimal methods of communication should account for parent preferences. To help inform communication strategies focused on early life obesity prevention, we employed human-centered design methodologies to identify parental perceptions, concerns, beliefs, and communication preferences about early life obesity risk.

METHODS

We conducted a series of virtual human-centered design research sessions with 31 parents of infants <24 months old. Parents were recruited with a human intelligence task posted on Amazon's Mechanical Turk, via social media postings on Facebook and Reddit, and from local community organizations. Human-centered design techniques included individual short-answer activities derived from personas and empathy maps as well as group discussion.

RESULTS

Parents welcomed a conversation about infant weight and obesity risk, but concerns about health were expressed in relation to the future. Tone, context, and collaboration emerged as important for obesity prevention discussions. Framing the conversation around healthy changes for the entire family to prevent adverse impacts of excess weight may be more effective than focusing on weight loss.

CONCLUSIONS

Our human-centered design approach provides a model for developing and refining messages and materials aimed at increasing parent/provider communication about early life obesity prevention. Motivating families to engage in obesity prevention may require pediatricians and other health professionals to frame the conversation within the context of other developmental milestones, involve the entire family, and provide practical strategies for behavioral change.

Exploring parents' provision of factors related to the establishment of physical activity between normal weight and overweight infants

PURPOSE

Infancy is a critical time for the prevention of obesity and establishment of healthy behaviors such as physical activity that help to control weight. A limited amount of research has examined if factors related to infant physical activity vary by infant weight status. Therefore, the purpose of this mixed methods triangulation study was to examine differences in motor development, the home environment, and infant-parent play behaviors as well as to explore how parents promote active play opportunities with normal weight infants (NWIs) and overweight infants (OWIs).

DESIGN AND METHODS

We used a mixed methods triangulated approach to combine quantitative and qualitative data strands to examine variables associated with active play in normal weight (n = 16) and overweight (n = 11) infants. Data were analyzed using a two-tailed Mann-Whitney U nonparametric test and a summative content analysis approach.

RESULTS

Although there were no differences in infants' motor development and parent play behaviors based on infant weight, several other differences were found. OWIs had less access to materials that stimulate locomotor movement. Further, parents of OWIs more often reported utilizing cognitive play strategies in comparison to parents of NWIs who more often reported using physical play strategies. Parents felt they were the greatest influence on their child's activity regardless of infant size. Importantly, all parents desired more specific guidelines on how to encourage active play and preferred this information was delivered by their healthcare provider.

PRACTICE IMPLICATIONS

To meet parents' desires and potentially improve infants' developmental outcomes through the establishment of healthy physical activity behaviors, pediatric nurses could provide more specific guidance on providing active opportunities for infants.

Exploring gender differences in infant motor development related to parent's promotion of play

This study explored how parents' promotion of play may impact gender differences in motor development of six-nine month old infants. Twenty-nine infants between six-nine months of age and their primary caregivers took part in assessments of anthropometry, motor development, video observations of play and a qualitative interview. Results revealed females had significantly higher scores for fine motor skills and significantly higher incidence of touching toys in an individual play scenario compared to males. Males had a higher intensity level of play during both play scenarios. Qualitative explorations found that parents perceived other adults such as surrounding family and friends to promote gender differences but not themselves; however, parents' verbal interactions with infants did appear to differ by gender. Parents of males more frequently made statements to promote gross motor skills while parents of females more frequently made statements to promote fine motor skills. While biological influences are suggested to play a role on gender differences of motor development early in life, environmental explanations related to socialization, gender-differentiated expectations and experiences amplify these differences to a greater degree than may have been previously considered during this time period.

Relationship Between Body Mass Index and Body Image Disturbances Among South African Mothers and Their Daughters Living in Soweto, Johannesburg

In South African families, a phenomenon of mothers' acceptance of stoutness coexists with their daughters' appreciation for thinness. A sample of N = 615 mother-and-daughter pairs was recruited to conjointly identify the relationships toward body image and body mass index between both groups by assessing body weight satisfaction, body esteem, and eating disorders risk. We observed higher prevalence of obesity in mothers and higher eating disorders risk in daughters, while mother-daughter relationships were identified for body mass index and psychometric dimensions. The high prevalence of obesity in mothers and their tolerance for stoutness could expose their daughters to eating disorders and obesity.

Describing the diurnal relationships between objectively measured mother and infant physical activity

BACKGROUND

Evidence for the importance of accumulating sufficient physical activity in the early years is mounting. This study aimed to determine the relationship between maternal and infant objectively measured physical activity, and to examine the diurnal interactions between these behaviours while accounting for potential covariates.

METHODS

Mothers and infants (n = 152 pairs; infants aged 3-24 months) were recruited from Soweto, South Africa, and physical activity was measured using a wrist worn accelerometer (Axivity AX3, Axivity Ltd., Newcastle-upon-Tyne, UK) for 3-7 days. Mothers completed sleep diaries recording night time-in-bed (used as a proxy for nocturnal sleep status) for themselves and their infant; and reported times during which their infant was in their personal care (caregiver status) for each day during the measurement period. Significant correlates of infant physical activity, as well as the interactions between mother's physical activity, day of the week, sleep status, and caregiver status, were included in panel regression analyses with infant physical activity as the outcome.

RESULTS

There was an equal distribution of boys and girls, and their age ranged from 2.6 to 24.5 months. The majority of mothers (73%) did not spend any time apart from their infant. During weekdays, the combined effect of mother's physical activity (β=0.11), the interactions between mother's physical activity and caregiver status (β=0.17), and sleep status (β= - 0.04) on infant physical activity was β=0.24; while during weekend days this association was β=0.21; and was largely moderated by the interaction between the mother being with the infant and her activity levels (β=0.23), but partly attenuated by mother's physical activity independent of other variables (β= - 0.04). For each hour of the day, for both mother and infant, peaks of physical activity were higher when the mother was not the primary caregiver.

CONCLUSIONS

Infant physical activity levels were strongly associated with their mother's activity levels particularly during the week; this relationship was stronger when mothers were more active while looking after their infant. Mothers should be encouraged to be active when looking after their children, particularly during the week, and to provide infants with as much opportunity to be active as possible.
