    <jats:sec><jats:title>Background</jats:title><jats:p>Food addiction (FA) is defined as hedonic eating behavior involving the consumption of highly palatable foods (i.e., ultra processed foods in quantities beyond homeostatic energy requirements). FA is present in a subset of patients with overweight or obesity and could contribute to the response to weight loss treatments.</jats:p></jats:sec><jats:sec><jats:title>Aim</jats:title><jats:p>Determine FA in individuals that fulfil the criteria of FA as measured by the YFAS 2.0, and its association with anthropometric and body composition variables in a clinical sample of patients undergoing weight loss treatment. Also, to determine the most prevalent FA criteria.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>An observational, analytical, and cross-sectional study was conducted. Sampling was non-probabilistic, convenience based. A total of 158 participants were recruited from two clinical centers (private and public) focused on managing non-communicable chronic diseases. The Chilean version of YFAS 2.0 was administrated through the online REDCap platform. Anthropometric measurements were measured, and body mass index (BMI) was calculated.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>The mean age was 47.8 (SD 14.9) and BMI 28.7 (SD 5.3) kg/m<jats:sup>2</jats:sup>. There were 12.7% patients who screened positive on the YFAS 2.0 Chilean version (3.2% for mild, 2.5% for moderate and 7.0% for severe), the mean symptom count was 2.2 (SD 2.6), with <jats:italic>withdrawal</jats:italic> being the most prevalent criterion (33.5%). FA patients had significantly higher body weight compared to non-FA subjects (<jats:italic>p</jats:italic> = 0.045). We observed a slight and significant correlation between FA symptom count and body weight (<jats:italic>p</jats:italic> = 0.020), waist circumference (<jats:italic>p</jats:italic> = 0.005), and BMI (<jats:italic>p</jats:italic> = 0.023).</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>This is the first study in Chile that showed that FA was present in patients undergoing weight loss treatment and was associated with anthropometric measurements. In addition, it showed that <jats:italic>withdrawal</jats:italic> was the most prevalent criterion. Future studies should investigate whether the presence of FA and the <jats:italic>withdrawal</jats:italic> criterion could contribute to suboptimal clinical response to weight loss treatment.</jats:p></jats:sec>

    <jats:p>Handgrip strength (HGS) is a well-established indicator of muscle strength and a reasonable clinical predictor of metabolic health and diseases. This study explores the association between relative muscular strength and abdominal obesity (AO) in healthy Chilean adults. A convenience sample was recruited (<jats:italic>n</jats:italic> = 976) between 2018 and 2020. The HGS was determined by dynamometry. The anthropometry (weight, height, waist, and mid-arm circumference) and physical activity were also measured. The relative HGS (RHGS) was calculated by dividing the maximum HGS of the dominant hand by the body mass index. The AO was defined as a waist circumference (WC) &amp;gt;88 cm for women, and &amp;gt;102 cm for men. From the sample, 52.6% were women, 56.4% had excessive weight, and 42.7% had AO. The absolute and RHGS were greater in men compared to women (<jats:italic>p</jats:italic> &amp;lt; 0.001) and were decreased with age in both sexes. We observed a moderate negative correlation between WC and RHGS (<jats:italic>rho</jats:italic> = −0.54, and <jats:italic>rho</jats:italic> = −0.53, for men and women, respectively). The RHGS was lower in individuals with AO, independent of age and sex (<jats:italic>p</jats:italic> &amp;lt; 0.05). For each cm increase in WC, the odds of low RHGS (&amp;lt;25th percentile) increased by 12 and 9% for men and women, respectively. The AO is related to higher odds for low RHGS (OR: 1.72; 95% CI: 1.23–2.41). In our sample of healthy adults, a higher AO was associated with a lower muscle strength measured by dynamometry.</jats:p>
