<jats:sec> <jats:title>Background</jats:title> <jats:p>Ultra-processed foods (UPF), most of which have hyper-palatable properties, have been implicated in overconsumption and adverse health outcomes, yet their association with food addiction (FA) remains underexplored in young adults.</jats:p> </jats:sec> <jats:sec> <jats:title>Aim</jats:title> <jats:p>To assess the association between marker foods for UPF consumption and FA in Chilean university students, comparing UPF consumption among individuals with and without FA.</jats:p> </jats:sec> <jats:sec> <jats:title>Methods</jats:title> <jats:p>In a cross-sectional study, 287 young adults (median age: 21 years) completed the NOVA Screener -which captures the presence and number of UPF items consumed during the previous day- and the Chilean version of the Yale Food Addiction Scale 2.0 (YFAS 2.0-Chile). Anthropometric measurements and body composition were obtained for 271 participants.

Participants with FA had significantly higher median NOVA scores for beverages, snacks, and total UPF consumption. FA was positively associated with greater consumption of UPF beverages (OR 1.48, <jats:italic>p</jats:italic>  = 0.014), snacks (OR 1.26, <jats:italic>p</jats:italic>  = 0.044), and NOVA score (OR 1.12, <jats:italic>p</jats:italic>  = 0.042).

<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.

<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) &gt;88 cm for women, and &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> &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> &lt; 0.05). For each cm increase in WC, the odds of low RHGS (&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>

<jats:p>Breakfast is one of the most important meals of the day. A good quality breakfast must include dairy products, cereals, and fruits. The aim of this study is to determine breakfast dietary patterns and their nutritional quality among Chilean university students. A cross-sectional non-probabilistic study was conducted in 200 university students between 18 and 27 years in Santiago, Chile. To identify dietary patterns and breakfast quality, a breakfast food survey was conducted. Patterns were identified by factor analysis. Most of the subjects (53%) ate breakfast daily, with a higher prevalence among females (60.2% vs. 43.7%, p < 0.05); 68% did not consume fruits and 17.5% had good breakfast quality, with no differences by sex. Four breakfast dietary patterns were identified: “dairy & cereals”, “healthy”, “traditional salty” and “traditional sweet” that together explained 35.6% of the total variance. There was no sex difference in predominant dietary patterns. The “dairy & cereals” and “traditional sweet” patterns were associated with regularly eating breakfast (β: −0.47, p = 0.001; β: −0.32, p = 0.020) and the “healthy” pattern with BMI ≥25 kg/m2 (β: 0.35, p = 0.024). In conclusion, breakfast quality was inadequate due to low fruit consumption and energy intake. The four identified patterns included cereals, bread, dairy, fats and sugars. Results may be usual in the planning of future interventions aimed at improving breakfast consumption and quality in university students.</jats:p>
