Pretreatment predictors of weight loss in a 12-month behavioral obesity treatment: a signal detection analysis of DIETFITS.

Objective: The objective of this study was to identify pretreatment predictors of weight loss in a 12-month behavioral obesity treatment that restricted either fat or carbohydrates.

Methods: Participants were 436 adults with overweight or obesity from the Diet Intervention Examining The Factors Interacting with Treatment Success (DIETFITS) trial. Signal detection analysis was used to identify which combinations of 51 pretreatment demographic, clinical, behavioral, and psychosocial variables, along with diet type (healthy low-fat vs.

Mothers' Experiences of Institutional Betrayal During Childbirth and their Postpartum Mental Health Outcomes: Evidence From a Survey of New Mothers in the United States.

Introduction: The purpose of this descriptive study was to explore the relationship between the experience of institutional betrayal (IB) during childbirth and postpartum mental health.

Methods: Women who had given birth within the last 3 years in the United States as of June 2021 were recruited via Qualtrics to complete an online survey. Participants (N = 588) answered questions about their birth experiences, including adverse medical events and experiences of IB.

Switching diets after 6-months does not result in renewed weight loss: a secondary analysis of a 12-month crossover randomized trial.

Weight change trajectory from diet and lifestyle interventions typically involves rapid weight loss followed by a weight plateau after approximately 6 months. Changing from one weight-loss diet to another at the time of the plateau could instigate renewed weight loss. Therefore, our secondary analysis aimed to assess trajectory of weight loss in a 12-month, randomized, cross-over study.

Dietary Patterns Among US Children: A Cluster Analysis.

Background: Most children in the United States consume low-quality diets. Identifying children's dietary patterns and their association with sociodemographic characteristics is important for designing tailored youth dietary interventions.

Objective: This study's objective was to use cluster analysis to investigate children's dietary patterns and these patterns' associations with sociodemographic characteristics.

Association of dietary adherence and dietary quality with weight loss success among those following low-carbohydrate and low-fat diets: a secondary analysis of the DIETFITS randomized clinical trial.

Background: Eating a high-quality diet or adhering to a given dietary strategy may influence weight loss. However, these 2 factors have not been examined concurrently for those following macronutrient-limiting diets.

Objective: To determine whether improvement in dietary quality, change in dietary macronutrient composition, or the combination of these factors is associated with differential weight loss when following a healthy low-carbohydrate (HLC) or healthy low-fat (HLF) diet.

The intersection of traumatic childbirth and obstetric racism: A qualitative study.

Background: Traumatic childbirth experiences are common in the United States - affecting a third to a fourth of mothers - with significant negative impacts on maternal health. Yet most research on traumatic childbirth focuses on white mothers' experiences. Drawing on a racially and ethnically diverse sample of mothers who experienced traumatic childbirth, this exploratory qualitative study examined Black, Latina, and Asian mothers' traumatic birth experiences and the role of obstetric racism in shaping these experiences.

Between a Rock and a Hard Place: COVID Concerns and Partnered U.S. Mothers' Employment during the COVID-19 Pandemic.

Shutdowns of in-person school and childcare in spring 2020 in response to the coronavirus disease 2019 (COVID-19) pandemic were associated with substantial reductions in mothers' labor force participation (LFP). By fall 2020, in-person school and daycare were more widely available, but mothers' LFP remained as low as it was in spring. Coincidently, by fall 2020, daily COVID deaths had also began to peak.

Obstetric gaslighting and the denial of mothers' realities.

Gaslighting is a type of abuse aimed at making victims question their sanity as well as the veracity and legitimacy of their own perspectives and feelings. In this article, we show how gaslighting can operate as a key, yet underexamined strategy of obstetric violence, or the institutional and interpersonal violation of women's rights during pregnancy, childbirth, and postpartum. We draw on forty-six in-depth, semi-structured interviews with mothers who experienced a traumatic childbirth to examine how obstetric providers gaslight mothers before, during and after childbirth when they deny - and thereby destabilize - mothers' realities.

Associations of Changes in Blood Lipid Concentrations with Changes in Dietary Cholesterol Intake in the Context of a Healthy Low-Carbohydrate Weight Loss Diet: A Secondary Analysis of the DIETFITS Trial.

In 2015, the Dietary Guidelines for Americans (DGA) eliminated the historical upper limit of 300 mg of dietary cholesterol/day and shifted to a more general recommendation that cholesterol intake should be limited. The primary aim of this secondary analysis of the Diet Intervention Examining the Factors Interacting With Treatment Success (DIETFITS) weight loss diet trial was to evaluate the associations between 12-month changes in dietary cholesterol intake (mg/day) and changes in plasma lipids, particularly low-density lipoprotein (LDL) cholesterol for those following a healthy low-carbohydrate (HLC) diet. Secondary aims included examining high-density lipoprotein (HDL) cholesterol and triglycerides and changes in refined grains and added sugars.

A randomized crossover trial on the effect of plant-based compared with animal-based meat on trimethylamine-N-oxide and cardiovascular disease risk factors in generally healthy adults: Study With Appetizing Plantfood-Meat Eating Alternative Trial (SWAP-MEAT).

Background: Despite the rising popularity of plant-based alternative meats, there is limited evidence of the health effects of these products.

Objectives: We aimed to compare the effect of consuming plant-based alternative meat (Plant) as opposed to animal meat (Animal) on health factors. The primary outcome was fasting serum trimethylamine-N-oxide (TMAO).

Tobacco Product Promotions Remain Ubiquitous and Are Associated with Use and Susceptibility to Use Among Adolescents.

Introduction: The decline in tobacco smoking among US adolescents has been exceeded by the exponential rise in nicotine vaping with an overall net gain in youth tobacco product use. While cigarette companies are restricted from advertising on television/radio, vaping promotions have been largely unrestricted. This study examined exposure to tobacco product promotions in a US sample of 1003 adolescents and its associations with product use and susceptibility to use.

Occupying multiple stigmatized identities: Smoking and unemployment stigmas among the unemployed.

Stigma - which involves stereotyping, discrimination, and status loss - is a central driver of morbidity and mortality. Given the de-normalization of smoking and the status loss of unemployment, unemployed individuals who smoke may occupy multiple stigmatized identities. As such, this study examined aspects and correlates of smoking and unemployment stigmas among unemployed job-seekers who smoke.

Integration of Tobacco Treatment Services into Cancer Care at Stanford.

As part of a National Cancer Institute Moonshot P30 Supplement, the Stanford Cancer Center piloted and integrated tobacco treatment into cancer care. This quality improvement (QI) project reports on the process from initial pilot to adoption within 14 clinics. The Head and Neck Oncology Clinic was engaged first in January 2019 as a pilot site given staff receptivity, elevated smoking prevalence, and a high tobacco screening rate (95%) yet low levels of tobacco cessation treatment referrals (<10%) and patient engagement (<1% of smokers treated).

Baseline Psychosocial and Demographic Factors Associated with Study Attrition and 12-Month Weight Gain in the DIETFITS Trial.

Objective: The purpose of this study was to examine correlates of failure-trial attrition and weight gain-in a randomized clinical weight-loss trial.

Methods: The Diet Intervention Examining The Factors Interacting with Treatment Success (DIETFITS) trial included 609 adults (18-50 years; BMI 28-40). Participants were randomized to a 12-month healthy low-fat or healthy low-carbohydrate diet for weight loss.

E-Cigarettes: Harmful or Harm-Reducing? Evaluation of a Novel Online CME Program for Health Care Providers.

Aim: Patients are asking health care providers about e-cigarettes, vaping, and other electronic nicotine delivery systems (ENDS). Provider advice on ENDS has varied greatly, suggesting a need for evidence-based continuing medical education (CME).

Setting: A novel free online CME course was developed on ENDS risks and benefits, product types (e.

You're worth what you eat: Adolescent beliefs about healthy eating, morality and socioeconomic status.

Amidst growing concern about adolescents' diets and dietary health in the United States, this article asks: what does healthy eating mean to adolescents? Using data from in-depth interviews conducted with 74 adolescents across socioeconomic status (SES) in California in 2015-2016, I show how adolescents view healthy eating as a moral, affluent practice and use discussions of healthy eating to assert their own morality and socioeconomic position. Adolescents associate healthy eating with 1) financial privilege and 2) moral superiority. Adolescents differ, however, in how they view their own families' healthy eating habits, and accordingly, their own moral worth.

How Food Rules at Home Influence Independent Adolescent Food Choices.

Purpose: The prevalence of unhealthy dietary behaviors among adolescents is high. We examined the effect of having health-oriented food rules at home on the healthiness of adolescents' independent food choices, and the necessity of parental oversight for such rules to be effective.

Methods: We surveyed a socioeconomically and racially diverse San Francisco Bay Area public high school in May 2017 (N = 1,246).

Table talk: How mothers and adolescents across socioeconomic status discuss food.

This article reports findings from a qualitative study of food practices among families of differing socioeconomic circumstances. Using in-depth interviews from sixty-two families in the San Francisco Bay Area in 2015-2016, we find socioeconomic differences in how mothers and adolescents talk about food. Across SES, mothers and adolescents engage in discussions about healthy eating.

Dining with dad: Fathers' influences on family food practices.

Scholars have documented multiple influences on family food practices. This article examines an overlooked contributor to family diet: fathers. Using 109 in-depth interviews with middle and upper-middle class mothers, adolescents, and fathers in the United States, I show how fathers can undermine mothers' efforts to provision a healthy diet.
