Background: Rising rates of psychological distress (symptoms of depression, anxiety, and stress) among adults in the United States necessitate effective mental wellness interventions. Despite the prevalence of smartphone app-based programs, research on their efficacy is limited, with only 14% showing clinically validated evidence. Our study evaluates Noom Mood, a commercially available smartphone-based app that uses cognitive behavioral therapy and mindfulness-based programming.

Background: Behavioral weight loss programs often lead to significant short-term weight loss, but long-term weight maintenance remains a challenge. Most weight maintenance data come from clinical trials, in-person programs, or general population surveys, but there is a need for better understanding of long-term weight maintenance in real-world digital programs.

Methods: This observational survey study examined weight maintenance reported by individuals who had used Noom Weight, a digital commercial behavior change program, and identified factors associated with greater weight maintenance.

Background: Midlife is a time of increased responsibilities for women who have multiple roles including taking care of children, caring for elderly parents, managing households, and working outside the home. With little time for themselves, women additionally experience stressful life events (SLEs). The purpose of this study was to describe the longitudinal patterns of SLEs of women during midlife and to identify predictors of the SLE longitudinal patterns using baseline data of socio-economic factors and demographic characteristics.

Background Aims: Lifestyle intervention remains the foundation of clinical care for patients with NASH; however, most patients are unsuccessful in enacting sustained behavioral change. There remains a clear unmet need to develop lifestyle intervention programs to support weight loss. Mobile health (mHealth) programs offer promise to address this need, yet their efficacy remains unexplored.

Objective: The aim of this study was to determine the effects of menstrual cycle phases (postmenses and premenses), self-report of premenstrual syndrome (PMS), late reproductive stages (LRS1 and LRS2), and early menopausal transition (EMT) stage (Stages of Reproductive Aging Workshop [STRAW]) on severity of five symptom groups.

Methods: A subset of Seattle Midlife Women's Health Study participants (n = 290) in either LRS1 or LRS2 or EMT (STRAW+10 criteria) provided daily symptom data for at least one full menstrual cycle during the first year of the study and reported current PMS. Symptom severity was rated (1-4, least to most severe) in the daily diary for five symptom groups (dysphoric mood, neuromuscular, somatic, vasomotor, and insomnia) identified earlier with the same sample ( Maturitas 1996;25:1-10).

Background: Overweight and obesity are serious public health concerns. As the prevalence of excess weight among individuals continues to increase, there is a parallel need for inexpensive, highly accessible, and evidence-based weight loss programs.

Objective: This weight loss trial will aim to examine the efficacy of the Noom weight loss program in comparison to a digital control after a 6-month intervention phase and a 24-month maintenance phase, with assessments continuing for 2 years beyond the intervention (to 30 months-after the baseline).

Background: The prevalence of anxiety, depression, and general distress has risen in recent years. Mobile mental health programs have been found to provide support to nonclinical populations and may overcome some of the barriers associated with traditional in-person treatment; however, researchers have voiced concerns that many publicly available mobile mental health programs lack evidence-based theoretical foundations, peer-reviewed research, and sufficient engagement from the public.

Objective: This study aimed to evaluate the feasibility, acceptability, and preliminary outcomes of Noom Mood, a commercial mobile cognitive behavioral therapy- and mindfulness-based program.

According to recent research, body positivity and self-compassion are key outcomes that are tied to better psychological and physical health. To date, it is unclear whether body positivity and self-compassion improve, stay constant, or deteriorate over the course of a weight management program, particularly one that addresses the psychological roots of behavior change. Additionally, beyond controlled settings, there are no studies on body positivity and self-compassion in individuals who choose to join a commercial weight management program.

Background: There is little understanding of men's weight loss outcomes and behaviors in self-directed contexts, such as digital commercial mobile weight management programs. This is an especially pressing question given that men often express disinterest in weight management programs and it is unknown how that manifests in self-directed environments. .

During behavioral weight management, individuals reflect on their progress and barriers through goal pursuit (goal setting and goal striving). Emotions during goal pursuit are largely unknown, and previous investigations of emotions in weight management have primarily relied on self-report. In this retrospective study, we used a well-validated computational text analysis approach to explore how emotion words changed over time during goal setting and striving conversations with a coach in a mobile weight loss program.

Mobile health (mHealth) interventions are ubiquitous and effective treatment options for obesity. There is a widespread assumption that the mHealth interventions will be equally effective in other locations. In an initial test of this assumption, this retrospective study assesses weight loss and engagement with an mHealth behavior change weight loss intervention developed in the United States (US) in four English-speaking regions: the US, Australia and New Zealand (AU/NZ), Canada (CA), and the United Kingdom and Ireland (UK/IE).

Importance And Objective: In 2001 Staging Reproductive Aging Workshop conferees described the late reproductive stage (LRS) of reproductive aging as preceding the onset of the menopausal transition, yet there has been little attention to this aspect of reproductive aging. The aim of this scoping review was to examine scientific publications characterizing the LRS to map what is known about this stage with particular focus on reproductive endocrine patterns, menstrual cycle changes, and symptoms.

Methods: The initial search strategy included PubMed and CINAHL searches for the phrase LRS and "human.

Purpose: To examine the undesirable stressful life events midlife women experience, including: 1) which life events midlife women reported most frequently; 2) which life events women rated as most undesirable; and 3) whether age, years of education, income, employment, race/ethnicity, marital status, being a parent, and the menopausal transition stage were associated with the impact scores of the life event categories.

Background: In addition to the menopausal transition, midlife is a time of increased responsibilities for women related to multiple roles such as taking care of children, caring for elderly parents, managing households, and working outside the home. These multiple roles put midlife women at risk for increased stress with little time for themselves in order to relieve stress.

Background: Midlife, the period of the lifespan between younger and older adulthood, has been described as a period of transition in women's lives. Investigators studying midlife have focused on women 40 to 65 years of age, who typically experience multiple social, psychological and biological challenges, among them the menopausal transition. Investigators have reported a diverse array of stressful events, for example, health concerns, family problems, work-related issues, deaths, frustrated goal attainment, and financial worries; however, none have identified which life events midlife women experience as the most salient.
