Perceptions of Parental Support for Physical Activity and Healthy Eating among School-age Children During COVID-19 pandemic.

Family routines play a key role in promoting child health behaviors. This study 1) describes changes in children's perceptions of physical activity (PA) and healthy eating family routines across three time points: pre-pandemic (2017-2020), early pandemic (2020), and mid-pandemic (2021); and 2) explores how sex, age, and pandemic-related economic stressors relate to changes. Children's perceptions of family routines were assessed using four subscales adapted from the Comprehensive Home Environment Survey: PA-policies, Diet-policies, Diet-rules, and PA-Diet-role-model.

Studying the impact of COVID-19 mitigation policies on childhood obesity, health behaviors, and disparities in an observational cohort: Protocol for the COVID-19 Family Study.

Background: COVID-19 pandemic control policies, including school closures, suspended extra-curricular activities, and social distancing, were introduced to prevent viral transmission, and disrupted children's daily routines, health behaviors, and wellness. This observational cohort study among 697 families with children or adolescents, based on the Family Stress Model, aims to: 1) evaluate pre- to during-pandemic changes in child health behaviors (diet, physical activity, sleep) and weight gain, 2) identify mechanisms explaining the changes, and 3) determine projected healthcare costs on weight gain and obesity. Each aim includes an examination by racial and ethnic, socioeconomic, and geographic disparities.

Effects of the termination of LC imidacloprid stress on the multigeneration adaptive strategies of population.

Matsumura (Hemiptera: Aphididae) is a major soybean pest that often poses a serious threat to soybean production. Imidacloprid is one of the commonly used insecticides to control the soybean aphid. To investigate the effect of termination of imidacloprid stress on the adaptive strategies of soybean aphid populations, we studied the growth, development, and related metabolism changes when the stress was terminated after 24 generations of imidacloprid stress on .

Food Insufficiency, Supplemental Nutrition Assistance Program (SNAP) Status, and 9-Year Trajectory of Cognitive Function in Older Adults: The Longitudinal National Health and Aging Trends Study, 2012-2020.

Background: Despite findings from cross-sectional studies, how food insecurity experience/Supplemental Nutrition Assistance Program (SNAP) status relates to cognitive decline over time has not been fully understood.

Objectives: We aimed to investigate the longitudinal associations between food insecurity/SNAP status and cognitive function in older adults (≥65 y).

Methods: Longitudinal data from the National Health and Aging Trends Study 2012-2020 were analyzed (n = 4578, median follow-up years = 5 y).

Promising trends and influencing factors of complementary feeding practices in Côte d'Ivoire: An analysis of nationally representative survey data between 1994 and 2016.

Poor complementary feeding (CF) challenges early childhood growth. We examined the trends and influencing factors of CF practices among children aged 6-23 months in Côte d'Ivoire. Using data from Demographic and Health Surveys (DHS, 1994-2011) and Multiple Indicator Cluster Surveys (MICS, 2000-2016), the trends and predictors of World Health Organization-United Nations International Children's Emergency Fund CF indicators including the timely introduction of complementary foods (INTRO), minimum meal frequency (MMF), minimum dietary diversity (MDD) and minimum acceptable diet (MAD) were determined.

Food Insecurity and Mental Well-Being in Immigrants: A Global Analysis.

Introduction: This study estimates the prevalence of food insecurity, mental well-being, and their associations among immigrants and compares the food insecurity-mental well-being associations with nonimmigrants globally and by region.

Methods: The Gallup World Poll data from 2014 to 2019 were analyzed in 2021. A total of 36,313 immigrants and 705,913 nonimmigrants were included.

Daily food insecurity is associated with diet quality, but not energy intake, in winter and during COVID-19, among low-income adults.

Background: Food insecurity (FI) is a dynamic phenomenon. Experiences of daily FI may impact dietary outcomes differently within a given month, across seasons, and before or during the COVID-19 pandemic.

Objectives: The aims of this study were to investigate the association of short-term FI with dietary quality and energy 1) over six weeks in two seasonal months and 2) before and during the COVID-19 pandemic.

Psychosocial Risk Factors for Food Insecurity in Puerto Ricans Living in the USA from Baseline to 5-Year Follow-Up.

Background: Food insecurity is prevalent among Puerto Rican adults in the USA and is associated with adverse psychosocial outcomes. However, the direction of this association has not been established in this understudied population.

Objectives: In this study, we aimed to examine the longitudinal association between a group of psychosocial risk factors and subsequent food insecurity in a cohort of Puerto Rican adults.

Food Insecurity and Cognitive Function in Middle to Older Adulthood: A Systematic Review.

Food insecurity (FI) may limit cognitive functioning during aging. The goal of this systematic review was to summarize existing evidence linking FI and general or specific cognitive functions in middle and older adulthood. A systematic search of human studies published between 1 January 2000 and 30 April 2018 was conducted in PubMed, PsycINFO, and CAB Direct.

Fabrication and oil adsorption of carbon nanotube/polyvinylpyrrolidone surface composite.

It needs to assemble the industrial CNT powders into macroscopic porous surface composite to utilize the surface properties of CNTs, as well as to prevent them entering into environments. We demonstrate a method to fabricate the surface composites from CNTs and polyvinylpyrrolidone (PVP) by electrospinning, where CNTs distribute firmly and mainly on the surface PVP nanofibers. The CNTs/PVP surface composites have high pore volume of 10 cc/g and remarkable CNTs load of 98%.
