Time allocation and dietary habits in the United States: Time for re-evaluation?

A dialectic of control and acceptance: Mealtimes with children on the autism spectrum

Shared family meals have important implications for child health and wellbeing, however, mealtimes with children on the autism spectrum are often characterized by stress and problematic behavior. A better understanding of the underlying processes can elucidate the mealtimes challenges that families with children on the spectrum face as well as how families overcome those challenges in order to promote family health and wellbeing. Through a grounded theory analysis of mealtime observations, parent interviews, and child interviews with 16 families in the United States, we identified a theory of A Dialectic of Control and Acceptance. Integral to the role of mealtimes is for parents to express love through control and acceptance, however, these parallel processes are in tension with one another. How parents negotiate this tension dictates the degree to which their expectations are well aligned with their children's strengths and challenges and are able to provide effective support.

Measuring Food Culture: a Tool for Public Health Practice

PURPOSE OF REVIEW

Food culture is a ubiquitous aspect of all societies. This review provides an overview of methods for measuring food culture, and emphasizes the importance of these measures not just for description, but also for strengthening public health practice, primarily through the development of better interventions; to monitor and evaluate changes in diet and nutrition; and for the development of strategies for sustainability and dissemination.

RECENT FINDINGS

Food culture measurement has enriched public health practice through its use of myriad approaches, including interviews, cultural domain analysis, visual methods, observation, time allocation studies, focus groups and community workshops, household studies, and textual analysis. Food culture measurement is essential for public health practice related to food and nutrition, and can lead to, among other outcomes, improved implementation research in nutrition, understanding household dynamics that impact nutritional outcomes, innovative textual analysis to identify food culture through language, and the selection of interventions conveyed through multiple strategies, including digital means, such as via social media.

Time Spent Eating, by Immigrant Status, Race/Ethnicity, and Length of Residence in the United States

Introduction

Time spent eating is associated with obesity and diet-related diseases. We examined the association between time adults spent eating, immigrant status, race/ethnicity, and race/ethnicity among adults in the United States.

Methods

We used multivariate linear regression to analyze a cross-sectional, nationally representative sample of respondents aged 19 years or older (N = 192,486) from the 2016 American Time Use Survey. The outcome measures were time spent per day on primary eating and drinking and secondary eating. The predictors were immigrant status, race/ethnicity, and years spent living in the United States.

Results

Multivariate adjusted minutes per day spent on primary eating and drinking were 66.4 for noncitizens, 66.5 for naturalized citizens, and 60.1 for US-born individuals. Multivariate adjusted minutes per day spent on secondary eating were 11.1 for noncitizens, 12.2 for naturalized citizens, and 12.9 for US-born individuals. Minutes per day spent on primary eating and drinking for immigrants by length of residence in the United States was 69.7 minutes for 5 years or less of residence, 67.9 minutes for 6 to 10 years of residence, 63.6 minutes for 11 to 15 years of residence, and 63.6 minutes for more than 15 years of residence. Minutes per day spent on secondary eating for immigrants by length of residence was 5.5 minutes for 5 years or less of residence, 9.7 minutes for 6 to 10 years of residence, 8.4 minutes for 11 to 15 years of residence, and 12.6 minutes for more than 15 years of residence.

Conclusion

Time spent eating varied by immigrant status and length of residence in the United States.

Mutual Relationship between Tau and Central Insulin Signalling: Consequences for AD and Tauopathies?

Alzheimer disease (AD) is a progressive neurodegenerative disorder mainly characterized by cognitive deficits and neuropathological changes such as Tau lesions and amyloid plaques, but also associated with non-cognitive symptomatology. Metabolic and neuroendocrine abnormalities, such as alterations in body weight, brain insulin impairments, and lower brain glucose metabolism, which often precede clinical diagnosis, have been extensively reported in AD patients. However, the origin of these symptoms and their relation to pathology and cognitive impairments remain misunderstood. Insulin is a hormone involved in the control of energy homeostasis both peripherally and centrally, and insulin-resistant state has been linked to increased risk of dementia. It is now well established that insulin resistance can exacerbate Tau lesions, mainly by disrupting the balance between Tau kinases and phosphatases. On the other hand, the emerging literature indicates that Tau protein can also modulate insulin signalling in the brain, thus creating a detrimental vicious circle. The following review will highlight our current understanding of the role of insulin in the brain and its relation to Tau protein in the context of AD and tauopathies. Considering that insulin signalling is prone to be pharmacologically targeted at multiple levels, it constitutes an appealing approach to improve both insulin brain sensitivity and mitigate brain pathology with expected positive outcome in terms of cognition.
