Objective: The purpose of this study was to investigate the reciprocal relationship between sedentary behavior (SB) and momentary affect in the context of daily experiences.
Methods: Community-dwelling midlife women (N = 121; age 40-60 y) were recruited for a 15-day daily diary study. The women rated their positive and negative affect when prompted on a personal digital assistant device four times per day and wore an accelerometer for objective assessment of SB. Multilevel models were estimated to test concurrent and lagged associations between momentary estimates of SB and affect.
Results: In models that controlled for day of week, number of hot flashes, and total minutes of accelerometer wear time, greater concurrent positive affect was associated with fewer minutes spent being sedentary (β = -31, P < 0.01). Neither lagged positive nor negative affect predicted later SB; however, more sedentary minutes predicted lower positive affect at the next occasion (β = -0.04, P < 0.01).
Conclusions: These results suggest that SB has negative affective consequences from moment to moment. The implications of reduced positive affect after prolonged bouts of SB for subsequent motivational, behavioral, or well-being outcomes remain to be determined.

Longitudinal Associations Between Youth Information Management With Mothers and Self-Esteem: The Role of a Sense of Control.
J Adolesc

Introduction: Adolescents' information management behaviors involve calibrating interactions between the self and parents, which could serve as either risk or protective factors for self-esteem. Since a sense of control over life outcomes is a protective factor for overall well-being, it might account for links between youth information management and self-esteem. This longitudinal study examined whether youth's sense of control mediated associations between concealment and voluntary disclosure and their self-esteem, at both the between- and within-person levels.

Anthropogenic land use change concurrent with introductions of non-native species alters the abundance and distribution of foraging resources for wildlife. This is particularly concerning when resource bottlenecks for wildlife are linked to spillover of infectious diseases to humans. Hendra virus is a bat-borne pathogen in eastern Australia.

Introduction: Studies using cross-sectional data or with a short follow-up period fail to distinguish whether the associations between sleep duration and physical activity with cognitive function result from reverse causation.
Methods: The longitudinal study examined the individual and joint associations, with specific temporality, between sleep duration and physical activity with cognitive function, using time-lagged linear mixed models and generalized additive mixed models.
Results: A total of 14,694 participants aged ≥ 50 years were included, with an average lagged time of 4.

Few studies have examined the bidirectional association between loneliness and functional limitations longitudinally. The current study aimed to explore the causal relationship between loneliness and functional limitations over time (2008 to 2016; T1-T3) using data from the Health and Retirement Study (HRS). Including 7,046 older American adults ( = 69.

Protein deficiency in the diet during pregnancy and lactation has a serious impact on the offspring by programming a predisposition to such serious diseases as hypertension and type 2 diabetes mellitus. In our study, we examined liver ultrastructure of rat pups at ages 2, 21, and 40 days with maternal protein deficiency. Body weight of the pups progressively lagged behind the control throughout the experiment, and the timing of eye opening indicated a slowdown of development.
