“…Since the development of the Yale Food Addiction Scale (YFAS) psychometric scale to measure FA, several studies have been conducted on this theme worldwide (Davis, 2017; Praxedes et al, 2022; Pursey et al, 2014). The scale has been translated and validated into Brazilian Portuguese (Nunes‐Neto et al, 2018) and Spanish (Granero et al, 2014; Granero et al, 2018), including with semantic adaptations for the Chilean (Marín, 2014) and Mexican populations (Valdés‐Moreno et al, 2016), and some studies using this scale have thus reported on the prevalence of FA in Latin American countries (Falcón et al, 2021; Filgueiras et al, 2019; Lopez‐Lopez et al, 2021; Obregón et al, 2015). However, to date, prevalence of FA in Latin American populations has not been systematically investigated, which is an important gap given the specificities of this group.…”

Objective Food addiction (FA) has been extensively investigated worldwide; however, the prevalence of FA in the Latin American population has yet to be established and past work has largely neglected the specificities of this region, that includes the most significant economic disparities in the world. Thus, the objective of this study was to assess the prevalence of FA measured by the Yale Food Addiction Scale in Latin America. Method The search was performed on MEDLINE, ScienceDirect, LILACS, IBECS, SciELO, PsycArticles, CENTRAL, and the gray literature. FA prevalence data were collected, and random effects meta‐analyses were performed to calculate the overall weighted prevalence, the prevalence by country, and by clinical and non‐clinical samples. Results A total of 10,082 occurrences were identified through database searches, and 23 studies were included (Mexico = 9; Brazil = 7; Chile = 4; Argentina = 1; Peru = 1; Uruguay = 1). The prevalence of FA found in clinical samples was 38% (95% CI: 16%–63%; I2 = 98.67%; 8 studies), while in non‐clinical samples, it was 15% (95% CI: 10%–21%; I2 = 98.51%; 15 studies). Discussion The average prevalence of FA in the Latin American countries included here was in accordance with that reported in other regions worldwide. It is noteworthy that the studies were conducted only in six countries, which are among those with the highest income in the region and do not represent the situation in native populations or those with lower purchasing power. This gap in the data also reflects the effects of economic disparities on the availability of empirical data in the region. Public Significance The prevalence of food addiction in Latin America was similar to that reported in other regions. It was higher among individuals with overweight, whether or not undergoing bariatric surgery, than in non‐clinical samples. These findings contribute to aggregate information about this condition that has drawn the attention of clinicians and researchers.

“…The rs2267717 variant located in the second intron of the CRHR2 gene at chromosomal position 30,677,427 was previously associated with openness personality, however, it was not associated with preterm birth 27 28. Finally, the rs2267716 variant, which is also located in the second intron of the CRHR2 gene in chromosomal position 30,677,027, was associated with food addiction and as a contributing factor to variability in acute bronchodilator response in Caucasian asthmatic individuals 29 30. However, there is little information about CRHR2 variants and cancer.…”

Colorectal cancer (CRC) is the third most common cancer and one of the main causes of death around the world. Multiple lines of evidence have suggested the role of the corticotropin-releasing hormone (CRH) family in CRC induction, including the low expression of corticotropin-releasing hormone receptor 2 (CRHR2), which is an angiogenesis inhibitor and inflammatory modulator. Previous research suggests that CRHR2 expression in colonic intestinal cells can regulate migration, proliferation and apoptosis through the modulation of several pathways. The aim of this study was to analyze the association of the rs10250835, rs2267716 and rs2267717 variants of CRHR2 gene with CRC in the Mexican population in order to consider its predictive value in CRC. This cross-sectional study included a group of 187 unrelated patients with sporadic CRC and a control group of 191 healthy blood donors. DNA extraction from peripheral blood was carried out using the Miller method. Identification of the rs10250835 variant was performed using PCR-restriction fragment length polymorphism (RFLP) and the rs2267716 and rs2267717 variants using TaqMan allelic discrimination assay. The minor allele homozygous CC of the rs2267716 variant of CRHR2 showed significant difference between CRC and control group (p=0.025), as well as the GCA haplotype (p=0.007), corresponding to the rs10250835, rs2267716 and rs2267717 variants, respectively. Our results suggest that the rs2267716 variant and GCA haplotype of CRHR2 represent a risk factor for CRC development in Mexican patients.
