Assessing basic and higher-level psychological needs satisfied through physical activity.

Background: There has been increasing interest in the extent to which the fulfillment of psychological needs is associated with physical activity engagement. However, a vast majority of studies consider only psychological needs such as relatedness, competence, and autonomy-with psychological needs such as challenge, creativity, and spirituality rarely being addressed. The aim of this study was to examine the preliminary reliability (i.

Exploring the Effects of Perceived Stress on the Within-Person Relationships Between Daily Activity Levels and Sleep in Women: An Ecological Momentary Assessment Study.

Background: Many studies show positive bidirectional associations between physical activity (PA) and sleep at the between-person level. There is an increased interest in investigating these associations at the within-person level. Few studies examined the effects of time-varying moderators on the within-person bidirectional associations between PA and sleep.

Children's Daily Negative Affect Patterns and Food Consumption on Weekends: An Ecological Momentary Assessment Study.

Objective: This study evaluated the association between children's daily negative affect (NA) trajectories and unhealthy food consumption during weekends using ecological momentary assessment (EMA).

Design: Children answered mobile phone-based EMA surveys 7 times a day for 2 weekend days per wave, with each survey assessing current NA and past 2-hour consumption of fried foods (chips or fries), sweets (pastries or sweets), and sugary beverages (drank soda or energy drinks).

Setting: Los Angeles, California.

Association of Breastfeeding Duration with 12-Month Postpartum Blood Lipids in a Predominately Lower-Income Hispanic Pregnancy Cohort in Los Angeles.

Breastfeeding may protect women’s long-term cardiovascular health; however, breastfeeding-related postpartum lipid changes remain unclear. We aim to examine associations of breastfeeding duration with maternal lipids at 12 months postpartum. In a subsample (n = 79) of the Maternal and Developmental Risks from Environmental and Social Stressors (MADRES) cohort, breastfeeding status and duration at 3, 6, and 12 months postpartum were self-reported.

Dyadic Effects of Pokémon GO on Physical Activity and Sedentary Behavior in Mothers and Children.

Family-based mobile health applications may be an opportunity to increase children's physical activity (PA) levels. Researchers have highlighted Pokémon GO as a potential model for future PA interventions as it integrates PA with social gamification. This study provides descriptive data on Pokémon GO usage among mothers and their children and examines differences in moderate to vigorous PA (MVPA) over time among individuals playing Pokémon GO compared to non-players using a dyadic subsample from a three-year longitudinal study.

Third trimester cortisol is positively associated with gestational weight gain in pregnant women with class one obesity.

Background/objective: Prevalence of pre-pregnancy obesity and excessive gestational weight gain (GWG) are higher among women of color with low SES. Dysregulation of the Hypothalamic-Pituitary-Adrenal (HPA) axis and its end-product, cortisol, during pregnancy is hypothesized to be associated with excessive GWG. However, past studies have produced inconsistent findings and often did not include health disparities populations.

Cross-sectional and longitudinal associations of park coverage, greenness exposure and neighbourhood median household income with children's depressive and anxiety symptoms.

Aim: Internalising symptoms and disorders often emerge in childhood and are associated with negative health outcomes into adulthood. Studies have shown neighbourhood characteristics (e.g.

Early effects of the COVID-19 pandemic on fertility preferences in the United States: an exploratory study.

Objective: To explore early disparate impacts of the COVID-19 pandemic on fertility preferences DESIGN: Cross-sectional study SETTING: Online survey questionnaire PATIENT(S): A total of 440 female participants who were trying to conceive (TTC) in the past year or currently are TTC.

Intervention(s): No interventions administered.

Main Outcome Measure(s): Change in fertility preference RESULT(S): Approximately 1 in 3 participants reported changing their fertility preferences because of the COVID-19 pandemic.

The mediating role of emotional eating in the relationship between perceived stress and dietary intake quality in Hispanic/Latino adolescents.

Obesity rates have steadily increased over the past three decades, and large racial/ethnic disparities in childhood obesity rates-specifically for Hispanic/Latino youth-highlight the major need for identifying and examining key mechanisms of obesogenic behaviors for this at-risk population. This study investigates the relationship between stress and dietary quality in Hispanic/Latino adolescents and seeks to determine the mediating role of emotional eating as a behavioral mechanism. Baseline data from 169 adolescents enrolled in the Imagine HEALTH trial were used to investigate these relationships.

Associations of Mothers' and Children's Stress With Children's Device-Measured Physical Activity and Sedentary Behavior Trajectories Across 3 Years.

Background: Psychological stress has adverse effects on health-related behaviors, yet longitudinal research is lacking. Research examined how children's and mothers' perceived stress are associated with children's physical activity and sedentary behavior trajectories across 3 years.

Methods: Mothers and their children (N = 186 dyads; 8-12 y at baseline, 57% Hispanic) completed 6 assessments across 3 years.

Momentary and personal characteristics predicting maternal fruit and vegetable preparation for children using ecological momentary assessment.

A large body of literature on child-focused research regarding healthy eating within the family context has focused on behavioral management strategies, such as reinforcement, or parental modeling through personal intake or encouragement. However, food preparation behaviors among mothers have been understudied. Also unknown is how maternal food preparation behaviors vary across population subgroups and contexts.

Internalizing symptoms modulate real-world affective response to sweet food and drinks in children.

The purpose of the current study was to examine affective response to sweet foods and drinks as a function of children's internalizing symptoms using ecological momentary assessment (EMA). A sample of 192 8-12-year-old children completed a self-report measure of internalizing symptoms and EMA prompts of affect and food intake for eight days, excluding time at school. There was an interaction between sweet food intake and internalizing symptoms for positive affect and for sweet drink intake and internalizing symptoms for negative affect.

Prenatal Maternal Cortisol Levels and Infant Birth Weight in a Predominately Low-Income Hispanic Cohort.

Infant birth weight influences numerous health outcomes throughout the life course including childhood obesity and metabolic morbidities. Maternal experience of stress, both before and during pregnancy, has been hypothesized to influence fetal growth and birth outcomes. However, these associations currently are not fully understood, due to conflicting results in the published literature.

Longitudinal associations of maternal stress and child stress with child body mass index trajectory.

Background: Although exposure to stress is common among children and their parents, longitudinal research on the effects of perceived stress on child obesity risk is lacking. This study examined the 3-year longitudinal associations of children and mothers' perceived stress with children's body mass index (BMI).

Methods: A sample of 199 mothers and their children (8-12 years at baseline, 56% Hispanic) completed six semi-annual assessments across 3 years with questionnaire-based self-report measures of perceived stress and measured height/weight.

Examining the same-day relationship between morning cortisol after awakening, perceived stress in the morning, and physical activity in youth.

Most children in the United States currently do not meet physical activity (PA) guidelines, and perceived stress is a known barrier against PA. However, most studies have solely focused on the between-subject (BS) association of stress and PA, whereas the within-subject (WS) relationship remains under-studied in children. This limits our understanding of day-level psychosocial factors that influence children's PA engagement.

Within-subject effects of environmental and social stressors on pre- and post-partum obesity-related biobehavioral responses in low-income Hispanic women: protocol of an intensive longitudinal study.

Background: Disproportionately high rates of maternal overweight and obesity among the Hispanic population before, during, and after pregnancy pose serious health concerns for both mothers (e.g., preeclampsia, gestational diabetes, weight retention) and children (e.
