“…Our data confirm those of Pagoto and colleagues' systematic review [4]; that men are less likely to take part in RCTs, and comprised 27% of all participants in their RCTs, compared with 37% in the studies providing data here. The Pagoto and colleagues' review did not focus on recruitment by sex in the same trial.…”

“…In a systematic review, Pagoto and colleagues [4] found that only 27% of participants in randomised trials were men, although the percentage was higher in interventions for obesity with related comorbidities (36% men). There was also a trend towards lower participation by men in group-based interventions (24%), compared with individual counselling (29%) or mail/e-mail/internet (34%); however, the male/female mix of the group-based interventions was not specified.…”

Twenty-two RCTs reported data separately for men and women in weight loss or weight maintenance interventions.We found men were under-represented in RCTs of weight loss interventions open to both sexes. Men comprised 36% of participants (4771 from 13,305 participants). Despite this, men were 11% (95% CI 8% to 14%, p<0.001) more likely to be trial completers compared to women. The trials did not report service user consultation and none were designed to investigate whether men and women responded differently to given interventions. Our meta-analysis of 13 trials showed no significant difference in weight loss between men and women, either for weight loss in kg ( p=0.90) or percentage weight loss (p=0.78), although men tended to lose more weight with intensive low fat reducing diets, with or without meal replacements, and structured physical activity/exercise programmes than women.Orlistat was less beneficial for men for weight maintenance. Individual support and tailoring appeared more helpful for men than women.We found evidence that men and women respond differently to, and have different preferences for, varying types of weight management programme. We suggest that it is important to understand men's views on weight loss, as this is likely to also improve the uptake and effectiveness of programmes for men.

“…The serving of a smaller portion of a complete meal may increase the likelihood of balanced intake than would eating patient-selected parts of a larger meal. Moreover, the recommended dietary intake is lower for women than for men, and women might be more concerned about their weight as has been reflected by the underrepresentation of men in clinical weight-loss trials (27). We are aware that sex also stands as a proxy for other patient characteristics such as weight, height, and body composition.…”

To eat or not to eat? Indicators for reduced food intake in 91,245 patients hospitalized on nutritionDays [2006][2007][2008][2009][2010][2011][2012][2013][2014] Geneva University Hospital, Geneva, Switzerland ABSTRACT Background: Inadequate nutrition during hospitalization is strongly associated with poor patient outcome, but ensuring adequate food intake is not a priority in clinical routine worldwide. This lack of priority results in inadequate and unbalanced food intake in patients and huge amounts of wasted food. Objectives: We evaluate the main factors that are associated with reduced meal intake in hospitalized patients and the differences between geographical regions. Design: We conducted a descriptive analysis of data from 9 consecutive, annual, and cross-sectional nutritionDay samples (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014) in a total of 91,245 adult patients in 6668 wards in 2584 hospitals in 56 countries. A general estimation equation methodology was used to develop a model for meal intake, and P-value thresholding was used for model selection. Results: The proportion of patients who ate a full meal varied widely (24.7-61.5%) across world regions. The factors that were most strongly associated with reduced food intake on nutritionDay were reduced intake during the previous week ( Conclusions: A set of factors that are associated with full meal intake was identified and is applicable to patients hospitalized in any region of the world. Thus, the likelihood for reduced food intake is easily estimated through access to patient characteristics, independent of world regions, and enables the easy personalization of food provision. This trial was registered at clinicaltrials.gov as NCT02820246.Am J Clin Nutr

“…Men are also underrepresented in obesity and weight loss research. Two systematic reviews that examined studies published between 1997-2004 and 1999-2009 found that only 27% of participants were male (Franz, VanWormer, & Crain, 2007;Pagoto, Schneider, Oleski, Luciani, Bodenlos, & Whited, 2011). Furthermore, only three of the 80 studies had male-only groups as opposed to 19 studies which had female-only groups.…”

Factors that influence overweight and obese men's participation in healthy eating, exercise, and weight management programs

FACTORS THAT INFLUENCE OVERWEIGHT AND OBESE MEN'S PARTICIPATION IN HEALTHY EATING, EXERCISE, AND WEIGHT MANAGEMENT PROGRAMSDespite the high prevalence of overweight and obesity in men, little is known about eating and exercise behaviors in this population. Additionally, research indicates that men are resistant to seeking help for weight concerns. Few studies, however, have assessed the need for specialized weight interventions designed for overweight and obese men. The present study attempted to gain an in-depth understanding of factors that influence overweight and obese men's engagement in healthy eating, exercise, and weight interventions through the use of qualitative methods.Research questions were developed using a framework that combined components of the theory of planned behavior and PRECEDE-PROCEED model. Six focus groups were conducted with 42 overweight and obese men living in Northern Colorado. Focus groups were recorded, transcribed, an analyzed using Ethnographic Content Analysis. Time, convenience, knowledge, social support, stigma, and masculinity emerged as important factors that influence men's weight-related health behaviors and help-seeking. Results provide support for the development of gender-sensitive weight interventions that take these factors into account.iii As the prevalence of obesity in the U.S. has dramatically increased in recent decades, researchers have attempted to better understand the etiology, prevention, and treatment of this disease. Given that an unhealthy diet and sedentary lifestyle are strongly associated with obesity, research on health behavior change plays an important role in working toward possible solutions.One major focus of obesity research has been to contextualize behaviors leading to obesity using various health behavior theories and to develop weight interventions according to these theories.Many of these theories acknowledge the powerful impact of the social environment on behavior.As such, a burgeoning focus of the literature has examined obesity in specific populations due to their differing social contexts. Although men comprise a significant proportion of the overweight and obese population, little is known about factors that influence men's eating, exercise, and weight management. Literature ReviewThe pervasiveness of obesity is problematic, especially considering the extensive evidence for medical conditions associated with the disease. Public health officials have declared obesity to be a nationwide epidemic. In the U.S., thirty-four percent of adults are obese and 68% are either overweight or obese (Flegal, Carroll, Ogden, & Curtin, 2010; Ogden, Yanovsky, Carroll, & Flegal, 2007). By 2015, obesity prevalence is projected to increase an additional six percent.Obesity accounts for 280,000 deaths annually in the U.S. (Manson, Skerritt, & Willett, 2002). After tobacco smoking, it is the second most preventable cause of death (United States Dietary Association [USDA], 2005). Obesity is also a risk factor for numerous health complicatio...
