Awareness and accuracy of height and weight among mothers and their preschool-aged children.

OBJECTIVES: A constant challenge in addressing the issue of obesity is the validity and reliability of self-reported measurements to calculate body mass index, that assesses the prevalence of obesity in a population. The objective of this study is to analyze both awareness and accuracy of mothers who are overweight or obese, in reporting their own and their child's height and weight measurements. STUDY DESIGN: cross-sectional study. METHODS: In this study, mothers were asked over phone to self-report height and weight for them and their child. This was followed by objective measurement of maternal and child height and weight by study staff in a clinical setting. The descriptive and statistical analysis of the data obtained were carried out using SAS software. RESULTS: 1) The mean weight of mothers who inaccurately self-reported their weight was 9.5 kg greater than the mean weight of those who reported accurately (P < 0.001). (2) Despite being aware of, and reporting their own measurements, 50% (n = 116) of mothers reported not knowing their child's height and 23% (n = 54) of them reported not knowing their child's weight. CONCLUSION: Strategies to tackle both maternal awareness and accuracy of child's measurements can help with early identification of child's obesity risk and prevention of long-term consequences.

Associations between feeding practices and maternal and child weight among mothers who do and do not correctly identify their child's weight status.

OBJECTIVE: This study aimed to explore factors associated with accuracy of maternal weight perception and determine if maternal feeding practices are associated with weight status. METHODS: Overweight/obese mothers reported demographics and perception of their child's weight and completed a modified preschooler feeding questionnaire. Mother's and child's height and weight were measured. Logistic regression was used to explore associations between demographic factors and accuracy. Correlations between the preschooler feeding questionnaire scales and mom's body mass index (BMI) and child's BMI-percentile were explored for the total sample and accurate and underestimating moms. RESULTS: Among mothers whose child was overweight or obese, only 20% of mothers correctly identified the child as overweight. Forty percent of moms were underestimaters. There was a positive correlation between concern the child was overweight/overeating and the child's BMI-percentile among underestimating moms; in the total sample (r = 0.32, p < .001) and accurate moms (r = 0.52, p < .001). In underestimaters only, there was a negative relationship between child BMI-percentile and pressure to eat (r = -0.30, p < .001) and concern about child underweight (r = -0.47, p < .001). CONCLUSIONS: This study identified different associations between child weight and mother's feeding practices in mothers accurately and inaccurately perceiving her child's weight. Intervention studies should explore targeting education on feeding practices based on these perceptions.

Worksite nutrition supports and sugar-sweetened beverage consumption.

OBJECTIVE: This study examined the link between worksite environmental supports for nutrition behaviours and sugar-sweetened beverage (SSB) consumption and offers insight into potential intervention points for reducing SSB consumption and combatting overweight and obesity. METHODS: Perceived worksite supports for healthy nutrition and self-reported SSB consumption were analysed for 2,015 working adults in the state of Missouri using a subset of questions from the Supports at Home and Work for Maintaining Energy Balance (SHOW-ME) study. RESULTS: Employees' use of vending facilities and the availability of water coolers/water bottles was significantly associated with increased SSB consumption, while use of cafeterias was significantly associated with decreased SSB consumption. Symbols or signs to identify healthy alternatives were significantly associated with sports drink consumption. CONCLUSIONS: This study supports previous work indicating the worksite as a necessary environment for nutrition interventions. When choices (vending and cafeteria) are provided, employees report making healthier decisions. For worksites without cafeterias, alternatives should be explored including mobile food trucks and farmer's markets.

Accessing evidence to inform public health policy: a study to enhance advocacy.

OBJECTIVES: Improving population health often involves policy changes that are the result of complex advocacy efforts. Information exchanges among researchers, advocates, and policymakers is paramount to policy interventions to improve health outcomes. This information may include evidence on what works well for whom and cost-effective strategies to improve outcomes of interest. However, this information is not always readily available or easily communicated. The purposes of this paper are to describe ways advocates seek information for health policy advocacy and to compare advocate demographics. STUDY DESIGN: Cross-sectional telephone survey. METHODS: Seventy-seven state-level advocates were asked about the desirable characteristics of policy-relevant information including methods of obtaining information, what makes it useful, and what sources make evidence most reliable/trustworthy. Responses were explored for the full sample and variety of subsamples (i.e. gender, age, and position on social and fiscal issues). Differences between groups were tested using t-tests and one-way analysis of variance. RESULTS: On average, advocates rated frequency of seeking research information as 4.3 out of five. Overall, advocates rated the Internet as the top source, rated unbiased research and research with relevancy to their organization as the most important characteristics, and considered information from their organization as most reliable/believable. When ratings were examined by subgroup, the two characteristics most important for each question in the total sample (listed above) emerged as most important for nearly all subgroups. CONCLUSIONS: Advocates are a resource to policymakers on health topics in the policy process. This study, among the first of its kind, found that advocates seek research information, but have a need for evidence that is unbiased and relevant to their organizations and report that university-based information is reliable. Researchers and advocates should partner so research is useful in advocating for evidence-based policy change.
