Quality of sexual life in Mexican men after spinal cord injury.

OBJECTIVE: To evaluate the quality of sexual life in men with spinal cord injury. DESIGN: Cross-sectional analytical study. PATIENTS: Males with a history of spinal cord injury who attended an outpatient rehabilitation service. METHODS: An analytical study examined adult male patients with complete spinal cord injury in rehabilitation. A modified Sexual Life Quality Questionnaire (SLQQ) examined quality of sexual life, with scores below 50 suggesting significant sexual dysfunction and dissatisfaction. The assessment evaluated age, occupation, marital status, comorbidities, and treatment methods. RESULTS: A total of 80 patients were included; 33 (41%) had a thoracic spinal cord injury, and 47 (59%) had a lumbar spinal cord injury. Thirty-seven patients (46%) were dissatisfied with the quality of their sexual life; 29 patients (88%) with thoracic spinal cord injury and 8 patients (17%) with lumbar spinal cord injury were dissatisfied with the quality of their sexual life (p = 0.001). Patients with higher education level experienced less sexual dissatisfaction (p = 0.03). CONCLUSION: Human sexuality involves numerous interconnected elements that impact on general health. Sexual pleasure, self-esteem, and personal relationships are crucial for patients with spinal cord injury to identify rehabilitation needs. These results indicate the importance of supporting sexual well-being in recovery. Further studies of sexual enjoyment and quality of life for patients with spinal cord injury are needed, using larger and more diverse populations.

Breastfeeding Practices and Postpartum Depression in Mexican Women during the COVID-19 Pandemic: A Cross-Sectional Study.

Background: Breastfeeding is a characteristic process of mammals that ensures delivery of an adequate nutritional supply to infants. It is the gold standard food source during an infant's first months of life. Since the onset of the COVID-19 pandemic in 2020, people in quarantine have experienced a wide range of feelings, which may make isolation challenging in terms of maternal health. This study focused on the prevalence of breastfeeding practices and postpartum depression (PPD) among Mexican women during the COVID-19 pandemic. Materials and Methods: This cross-sectional study included 586 postpartum women who completed an online survey 4-8 weeks after delivery from April to December 2020 in Guadalajara, Mexico. The aim was to identify potentially depressed mothers according to the Edinburgh Postnatal Depression Scale (EPDS) and describe their breastfeeding practices. Results: The mean maternal age was 30.4 ± 4.6 years, the mean EPDS score was 9.6 ± 5.0, and the PPD prevalence according EPDS scores was 27.1%. Exclusive breastfeeding (EBF) was reported by 32.3% of mothers in the first 48 h and by 70.3% of mothers 48 h after delivery. EBF was associated with a lower prevalence of PPD during the first 48 h (p = 0.015) and after the first 48 h (p = 0.001) after delivery. Skin-to-skin contact (SSC) was reported by 385 (65.7%) mothers. PPD was less frequent in mothers practicing SSC (20.3%) than it was in those not practicing SSC (40.3%) (p = 0.001). A higher percentage of mothers practiced SSC breastfed (66.9%) and used EBF (150, 79.4%) (p = 0.012 and 0.001, respectively). Conclusions: Results suggest that the pandemic emergency and restrictions imposed on the population significantly affected the well-being of mothers after birth, and that these effects may have posed risks to the mental health and emotional stability of postpartum mothers. Therefore, encouraging BF or EBF and SSC may improve or limit depressive symptoms in postpartum mothers.

Comparison of Fear of COVID-19 in Medical and Nonmedical Personnel in a Public Hospital in Mexico: a Brief Report.

The world is social distancing, and compulsory confinement has caused stress, psychological instability, stigmatization, fear, and discrimination in the general population. In this cross-sectional survey study, we administered the Fear of COVID-19 Scale (FCV-19S) to hospital medical and nonmedical personnel. A total of 1216 participants were surveyed from May 25 to May 29 of 2020. We asked all the staff for their participation in the study, and physical copies of the survey were distributed to the staff willing to participate. All surveys were answered anonymously. We found that the global FCV-19S mean score was 16.4 ± 6.1, with a significant difference between women and men's scores. Medical students presented higher scores than experienced medical personnel. Additionally, the medical and nursing personnel presented a higher level of fear than hospital staff who did not work directly with COVID-19 patients. Our findings suggest that greater knowledge of medicine or infectious diseases could decrease the overall psychological impact of the pandemic disease.

Prevalence of Depression, Anxiety, and Stress in Junior High School Students in Guadalajara, Mexico: A Cross-Sectional Survey Study.

Confinement and a lack of social interaction are associated with depressive symptoms, low self-esteem, and suicidal thoughts. We report the results of a cross-sectional survey of 1414 junior high school students. The aim was to evaluate the prevalence of depression, anxiety, and stress in Guadalajara, Mexico, during the COVID-19 pandemic. Mean scores on the validated Spanish version of the Depression, Anxiety, and Stress Scale (DASS-21) were found to be 6.15 ± 5.6 for depression, 5.8 ± 5.2 for anxiety, and 8.08 ± 5.3 for stress. Female students scored higher in all three conditions (p < 0.001). Students who had relatives infected with COVID-19 showed significantly more anxiety than those who did not (p < 0.004). Although certain demographic groups are at higher risk of manifesting depression, anxiety, and stress, the student population has also been affected by the global impact of the pandemic.

Prevalence of Dysexecutive Symptoms in High School Students during the COVID-19 Pandemic.

This is an observational cross-sectional study designed to ascertain the prevalence and severity of dysexecutive symptoms in high school students during the COVID-19 pandemic. The validated Spanish version of the Dysexecutive Questionnaire (DEX) was used. A total of 2396 participants aged 14-22 years were included. Our sample yielded a mean DEX scale score of 28.14 ± 17.42. By the DEX classification, 889 (37.1%) students achieved optimal scores, 384 (16%) reported mild dysexecutive symptoms, 316 (13.2%) reported moderate dysexecutive symptoms, and 807 (33.7%) reported strong dysexecutive symptoms. We found a significant difference between those with and those without employed mothers, with the former scoring higher (p = 0.004), the same as those with both parents employed (p = 0.004). Adolescents face emotional susceptibility and changes in their family, social, and educational environment related to isolation, resulting in altered emotional responses and social interaction.

Prevalence of Depression, Anxiety, and Stress among High School Students during the COVID-19 Pandemic: A Survey Study in Western Mexico.

Social isolation and school closure may predispose adolescents to higher prevalence rates of depression, anxiety, and stress. In this cross-sectional observational study, the validated Spanish version of the Depression, Anxiety, and Stress Scale was administered to 3112 students aged 14-22 years old. We also collected data on participant gender, age group, school shift (morning or afternoon), school year, family type, whether they or any first-degree relative had been infected with COVID-19, whether any family member had died of COVID-19, and whether either of their parents worked. Mean scores were 8.34 ± 6.33 for depression, 7.75 ± 5.89 for anxiety, and 10.26 ± 5.84 for stress. Female students presented significantly higher scores on all three measures compared with male students. Students who had been infected with COVID-19, who had an infected family member, or who had a family member who died of COVID-19 also presented higher scores on all three measures. Identifying the symptoms and warning signs of depression and anxiety disorders is critical, particularly in vulnerable populations like adolescents.

Preventive measures against the COVID-19 pandemic in Mexico: A cross-sectional study.

Introduction: Understanding how Mexicans behave during the pandemic could present a complete picture of the phenomenon in our country and provide better management of it. Objective: This study aimed to analyze the Mexican population's behavior and preventive measures. Methods: This was a cross-sectional study in which a total of 4,004 participants from the general population responded to the survey. Results: Almost 99% of the participants mentioned knowing the symptoms of COVID-19. Although 77.5% of participants considered that they followed proper social distancing measures, 60% of them mentioned that they knew at least six individuals who did not follow social distancing measures. Furthermore, 96.2% of participants reported using preventive measures at least 50% of the time. Only 51.3% used a certified mask. Conclusion: The COVID-19 pandemic outcomes in Mexico are the result of multiple negative factors, such as high rates of comorbidities, high number of people living together at home, many people breaking social isolation, and most of the population using non-certified preventive measures that may not be effective enough.

Treatment of melasma with platelet-rich plasma: A self-controlled clinical trial.

Melasma is a common circumscribed hypermelanosis of sun-exposed areas of the skin. Platelet-Rich Plasma therapy has been evidenced to inhibit melanin synthesis in animals and humans. To determine the effectiveness of platelet-rich plasma as a treatment for melasma. Twenty female patient with melasma were involved in this study. The intervention included three Platelet-Rich Plasma application sessions at 15-day intervals. Patients were evaluated before and after treatment. Variables measured included the facial melanin concentration using the melasma area and severity index score, melasma quality of life scale satisfaction grade, and histologic changes. Mean age was 41 ± 7 years. An initial MELASQOL score of 42 ± 14.8 and final score of 16.6 ± 7.2 (p = 0.008) were reported; the initial and final MASI score were 15.5 ± 8.4 and 9.5 ± 7.2 (p = 0.001), respectively. The dermatoscopy examination revealed a decrease in pigmentation after intervention (p = 0.001). Histopathologic improvement was detected in reductions in cutaneous atrophy (14 [70%] vs. 11 [55%]), solar elastosis (15 [75%] vs.11 [55%]), and inflammatory infiltrate (9 [45%] vs. 6 [30%]), before and after treatment, respectively. The intervention was associated with decreased intensity of the melasma patch and improved skin quality, shown by the MELASQOL and MASI scores.

Misinformation About and Interest in Chlorine Dioxide During the COVID-19 Pandemic in Mexico Identified Using Google Trends Data: Infodemiology Study.

BACKGROUND: The COVID-19 pandemic has prompted the increasing popularity of several emerging therapies or preventives that lack scientific evidence or go against medical directives. One such therapy involves the consumption of chlorine dioxide, which is commonly used in the cleaning industry and is available commercially as a mineral solution. This substance has been promoted as a preventive or treatment agent for several diseases, including SARS-CoV-2 infection. As interest in chlorine dioxide has grown since the start of the pandemic, health agencies, institutions, and organizations worldwide have tried to discourage and restrict the consumption of this substance. OBJECTIVE: The aim of this study is to analyze search engine trends in Mexico to evaluate changes in public interest in chlorine dioxide since the beginning of the COVID-19 pandemic. METHODS: We retrieved public query data for the Spanish equivalent of the term "chlorine dioxide" from the Google Trends platform. The location was set to Mexico, and the time frame was from March 3, 2019, to February 21, 2021. A descriptive analysis was performed. The Kruskal-Wallis and Dunn tests were used to identify significant changes in search volumes for this term between four consecutive time periods, each of 13 weeks, from March 1, 2020, to February 27, 2021. RESULTS: From the start of the pandemic in Mexico (February 2020), an upward trend was observed in the number of searches compared with that in 2019. Maximum volume trends were recorded during the week of July 19-25, 2020. The search volumes declined between September and November 2020, but another peak was registered in December 2020 through February 2021, which reached a maximum value on January 10. Percentage change from the first to the fourth time periods was +312.85, -71.35, and +228.18, respectively. Pairwise comparisons using the Kruskal-Wallis and Dunn tests showed significant differences between the four periods (P<.001). CONCLUSIONS: Misinformation is a public health risk because it can lower compliance with the recommended measures and encourage the use of therapies that have not been proven safe. The ingestion of chlorine dioxide presents a danger to the population, and several adverse reactions have been reported. Programs should be implemented to direct those interested in this substance to accurate medical information.

Substance Use and Psychological Distress in Mexican Adults during COVID-19 Pandemic: A Cross-Sectional Study.

OBJECTIVES: This observational cross-sectional study examined changes in substance use during the coronavirus disease 2019 (COVID-19) pandemic in the Mexican population and evaluated whether depression or anxiety was associated with these new consumption patterns. METHODS: An online survey was distributed to the general population. Participants were questioned about their demographics, situation during the COVID-19 pandemic, and substance consumption patterns. The Patient Health Questionnaire-9 for depression and the Coronavirus Anxiety Scale were used. RESULTS: A total of 866 individuals completed the survey. The mean scores for the Patient Health Questionnaire-9 and Coronavirus Anxiety Scale were 8.89 ± 6.20 and 3.48 ± 3.22, respectively. The preferred substances were alcohol (19%), tobacco (16.5%), and marijuana (5.6%). Consumption of alcohol (p = 0.042) significantly increased during the pandemic and it was higher in women than in men (p = 0.040). CONCLUSIONS: Substance use patterns were affected by the pandemic, with an increase in the number of users and consumption rate, as well as the reported psychiatric symptoms.

Effects of Oral Zafirlukast, Sildenafil, or Pirfenidone on the Formation of Postsurgical Intra-Abdominal Adhesions in an Experimental Rat Model.

INTRODUCTION: Intra-abdominal adhesions' main etiology is surgical procedures that commonly require reintervention. Oral treatments with sildenafil, zafirlukast, and pirfenidone have yielded decreased severity of fibrotic phenomena secondary to the introduction of foreign material. This study aimed to evaluate the efficacy of oral zafirlukast, sildenafil, or pirfenidone treatment on reducing or preventing intra-abdominal adhesions in an experimental rat model. METHODS: Four groups, each of 10 male Wistar rats weighing 250-300 g, were used. A midline laparotomy was used to excise an area of 1.5 × 1.5 cm and reconstructed with polypropylene mesh fixed to the abdominal wall. After 12 h, oral doses of zafirlukast (1.25 mg/kg, group B), sildenafil (15 mg/kg, group C), or pirfenidone (500 mg/kg, group D) were given every day for 8 days. The control group, A, received no treatment. At day 9, animals were reoperated. The implant was resected after ethically approved euthanasia, and specimens were fixed in 10% formaldehyde for histopathology. RESULTS: Control group A yielded adhesions with greater fibrovascular density and neighboring organ involvement than the other groups (p = 0.001), as well as intense inflammatory infiltrates and numerous granulomas (p = 0.04). Adhesions in group C had less fibrovascular density (p = 0.03) with decreased serosal injuries (p = 0.001) and less organ involvement. Group D had reduced adhesions without organ involvement (p < 0.01) and less inflammatory infiltrates, collagen fibers, and foreign body granulomas than group B or C (p < 0.01). CONCLUSIONS: Oral administration of these agents did not prevent adhesions but ameliorated them. Oral pirfenidone offered the best performance and could be recommended for human use.

Differences in Postoperative Pain, Nausea, and Vomiting After Elective Laparoscopic Cholecystectomy in Premenopausal and Postmenopausal Mexican Women.

BACKGROUND: Postoperative symptoms and pain after laparoscopic cholecystectomy (LC) are common in women. However, there is no evidence of differences in incidence and severity among different age groups. We evaluated whether adverse postoperative symptoms were more common in younger than in older women after LC. METHODS: One hundred and fifty premenopausal (mean age 37.6 ± 3.6 y) and 145 postmenopausal women (59 ± 5.2 y) were included in this retrospective cohort study. Clinical and anthropometric parameters were analyzed. Study endpoints were the incidences of postoperative nausea and vomiting (PONV) and pain, and the additional analgesics and antiemetics needed after surgery. RESULTS: Body mass index was normal in 42.7% of patients in the younger group and 64.8% in the older group (P < 0.001). Reported pain was more frequent and intense in the younger group throughout the study period (P < 0.01). Additional narcotics were required in 18% of premenopausal versus 7.6% of postmenopausal women (P = 0.001), and the doses used to reduce pain were higher for premenopausal women (P = 0.02). PONV was more frequent in the younger group at 1 and 6 h after surgery (P < 0.005). Rescue antiemetics were required in 29 premenopausal and 13 postmenopausal women (P = 0.01). Hospital stay was shorter for the older patients (P = 0.01). Minor morbidity was observed in both groups (0.7% and 2.1%). There was no mortality. CONCLUSIONS: Early PONV and pain after LC were more frequent in premenopausal women, who also required more rescue analgesic and antiemetic medication.

Anxiety and COVID-19: Coronavirus Anxiety Scale scores in medical and non-medical personnel in urban hospitals in Guadalajara. A cross-sectional survey study.

The world is facing the worst health crisis in modern history. In addition to general concerns about the effects of COVID-19 on health, hospital personnel are developing numerous mental health conditions. This cross-sectional survey study evaluated the prevalence and severity of anxiety caused by the COVID-19 pandemic using the Coronavirus Anxiety Scale (CAS) in 2136 hospital employees. For the employees who presented scores ranging from 1-20 (n = 1090, 51%), the CAS mean score was 4.22 (SD = 3.95). The mean score was higher in women than men. By work category, non-clinical hospital personnel presented the highest CAS scores.

Fear of COVID-19 Scale for Hospital Staff in Regional Hospitals in Mexico: a Brief Report.

The presence of COVID-19 has had psychological consequences among health personnel; these include fear, anxiety, and depression. In the current study, we used the Fear of COVID-19 Scale (FCV-19S) to assess the response to fear within health staff in Mexico. This was a cross-sectional survey study in which we administered the Spanish version of the FCV-19S to hospital staff. The FCV-19S is a seven-item questionnaire that assesses the severity of fear caused by COVID-19. A total of 2860 participants-1641 female and 1218 male personnel from three hospitals-were included in the study. The internal reliability of the scale was good, with Cronbach's alpha of .902. A confirmatory factor analysis (CFA) was conducted on the seven items of the FCV-19S, showing good model fit (χ 2 (7) = 29.40, p < .001; CFI = .99; TLI = .99; RMSEA = .03; SRMR = .010; AIC = 71.40). We found a global FCV-19S mean score of 19.3 ± 6.9, with a significant difference in scores between women and men. Our survey shows a significantly higher level of fear in nursing and administrative personnel, which may be explained by the nursing staff being in close contact with infected patients and the administrative staff lacking understanding of the possible implications of the infection, compared with nonclinical hospital personnel. Our results are consistent with those of other researchers. We must remember that fear is a reaction and that we must be courageous enough to trust validated infection prevention practices to provide the highest standard of care, in the safest environment that we can, for as long as we can.

Effect of a preoperative single-dose steroid on pulmonary function and postoperative symptoms after modified radical mastectomy: results of a randomized clinical trial.

BACKGROUND: Evidence suggests that a preoperative single-dose steroid improves lung function and decreases the incidence of postoperative symptoms; however, this has not been sufficiently proved in modified radical mastectomy for cancer. This study aimed to evaluate the efficacy of preoperative single-dose steroid administration for postoperative lung function and postoperative symptoms in women undergoing modified radical mastectomy for breast cancer. METHODS: In this controlled clinical trial, conducted between June 2014 and October 2018, we examined 81 patients. Patients received a preoperative single dose of 8 mg dexamethasone (n=41; treatment group) or placebo (sterile injectable water; n=40; control group). We obtained data on postoperative nausea and vomiting and pain intensity and performed spirometry 1 h before and 1, 6, 12, and 24 h after surgery. The use of additional analgesic or antiemetic drugs was recorded. We followed up patients 30 days after discharge and recorded any surgical or medical complications. RESULTS: The age distribution and anthropometric variables of the two groups were similar. Almost 50% of the patients in each group also underwent breast reconstruction. In the treatment group, pain intensity was always lower, the incidence of postoperative nausea and vomiting was lower at 6, 12, and 24 h, and additional analgesics or antiemetics were required less frequently (P<0.05 for all). Both treatment and control groups demonstrated a restrictive ventilatory pattern immediately after surgery, which in the treatment group was reversed after 24 h. However, the reconstructed patients had a more intense and prolonged restrictive pattern (P<0.05). Surgical morbidity included one seroma observed in the control group. No infections occurred at the surgical site or at any other level, and no patient developed any metabolic disorder. No mortality was observed in either group. CONCLUSIONS: This study establishes that a single preoperative dose of dexamethasone markedly decreased the incidence of postoperative nausea and vomiting and pain, improved respiratory parameters, and decreased the need for additional postoperative analgesic or antiemetic drugs. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov (ID NCT02305173).

Diagnostic utility of the serum-ascites albumin gradient in Mexican patients with ascites related to portal hypertension.

BACKGROUND AND AIM: Analysis of ascitic fluid is necessary to determine the etiology and to distinguish portal hypertension (PH)-related and unrelated ascites. Numerous diagnostic parameters have been studied, but no single parameter has completely distinguished these. We aimed to validate the serum albumin-ascites gradient (SAAG) for the diagnosis of ascites secondary to PH and to establish cutoff points to predict PH using its sensitivity and specificity. METHODS: This was a cross-sectional study conducted on patients diagnosed with ascites of any etiology. The SAAG and albumin concentration in ascitic fluid (AFA) were measured to establish their sensitivity and specificity for determining the presence or absence of PH. Cutoff points and levels of statistical significance were established based on the area under the curve. RESULTS: Eighty-seven patients were evaluated, of whom 74 (84%) were men, with an average age of 54.0 ± 13.6 years. Seventy-two (83%) were diagnosed at admission with PH-related ascites and 15 (17%) with non-PH-related ascites. SAAG correctly classified 48 (67%) patients, but 24 (33%) were classified incorrectly, while AFA classified 59 (82%) correctly and only 13 (17%) incorrectly. The diagnostic accuracy of SAAG was 57 versus 73% for AFA. AFA had a sensitivity of 82% and specificity of 66% (95% confidence interval [CI]: 0.63-0.93), while SAAG had a sensitivity of 66% but a specificity of 86% (95% CI: 0.72-0.95). CONCLUSIONS: The SAAG showed poor diagnostic performance with low sensitivity but high specificity. The diagnostic accuracy of AFA is superior to that of SAAG in discriminating between PH and non-PH ascites.

Gender Differences in Postoperative Pain, Nausea and Vomiting After Elective Laparoscopic Cholecystectomy.

BACKGROUND: Although reports suggest that pain and postoperative nausea and vomiting (PONV) may be more frequent in women, the evidence is inconsistent. The objective of this study was to investigate whether women are more sensitive to pain and PONV after laparoscopic cholecystectomy (LC). METHODS: A total of 370 women and 275 men were included in a retrospective cohort study. All underwent LC under standardized general anesthesia. The variables analyzed included clinical and anthropometric parameters. End points were the incidence of nausea, vomiting, pain, and the requirement for additional pain relievers and antiemetics to control these. RESULTS: The women were younger and had lower body weight than the men (p < 0.001). Body mass index was within the normal range for 50% of women and 30% of men (p < 0.001). Pain was more common in women at 1, 6, 12 and 24 h after surgery (p < 0.02). Narcotics in addition to the doses used to lessen pain intensity (p = 0.01) were required in 60 women and 19 men (p < 0.001). PONV was more frequent in women at 1 and 6 h after surgery (p < 0.01). Rescue antiemetics were required in 35 women and 11 men (p = 0.008). Hospital stay was shorter for men (p < 0.001). Four patients in each group developed postoperative complications (p = 0.14). There was no mortality. CONCLUSIONS: Early postoperative pain, nausea and vomiting after LC were more common in women, who more frequently required analgesic and antiemetic rescue medication.

[Anxiety in the presence of food in schoolchildren of Baja California Sur]. / Ansiedad en presencia de alimentos en escolares de Baja California Sur.

INTRODUCTION: Introduction: many obese children will be obese adults unless they adopt and maintain healthy eating and physical activity patterns. Anxiety has been described in overweight and obese children with dysfunctional family environments, with impact on their quality of life; risk for some eating disorder was also found. Objective: to identify anxiety in the presence of food in schoolchildren in Baja California Sur. Material and methods: a cross-sectional study in 406 schoolchildren, from 8 to 13 years of age, was performed: nutritional status calculation, measurements of attitudes towards food (cut-off point > 20), socioeconomic level, type of family, and intake of junk food were collected. Descriptive statistics and association measures were performed using Student's t-test and the chi-squared test. Parents provided their informed consent, and children provided their assent. Results: a total of 406 schoolchildren were evaluated, with ages of 10.4 ± 1.2. Of these, 53 % had healthy weight, 44 % had overweight or obesity, and 3 % were underweight. Functional families predominated at 67 %. A middle socioeconomic level was found in 64 %. In all, 94 % consumed junk food. There is an association between anxiety in the presence of food and socioeconomic status, and anxiety in the presence of food and nutritional status (p = 0.01). In overweight and obese schoolchildren no association was found between study variables. There is anxiety in the presence of food in 40 % of the sample due to external factors, in 5 % because of tiredness or boredom, in 11 % because of negative feelings. Conclusion: there is an association between anxiety, socioeconomic status, and nutritional status. Anxiety in the presence of food occurred in 54.7 % of cases.

INTRODUCCIÓN: Introducción: muchos niños obesos serán adultos obesos a menos que adopten y mantengan patrones saludables de alimentación y actividad física. Se han descrito: ansiedad en niños con sobrepeso y obesidad en ambientes de familias disfuncionales, repercusión en la calidad de vida y riesgo de algún desorden alimenticio. Objetivo: identificar la ansiedad en presencia de alimentos en escolares de Baja California Sur. Material y métodos: estudio de tipo encuesta trasversal en 406 escolares de 8 a 13 años de edad; se realizó un cálculo del estado nutricional y se efectuó una medición del test de actitudes hacia la alimentación (punto de corte de > 20); se recopilaron el nivel socioeconómico, el tipo de familia y la ingesta de comida chatarra. Se realizó una estadística descriptiva con medidas de asociación mediante la prueba t de Student y prueba de chi2. Se obtuvieron el consentimiento informado de los padres y el asentimiento del menor. Resultados: se evaluaron 406 escolares con edades de 10,4 ± 1,2. El 53 % presentaron peso saludable, el 44 % sobrepeso y obesidad, y el 3 % bajo peso. Predominó la familia funcional con un 67 %. Se consttó un nivel socioeconómico medio en el 64 %. El 94 % consumen alimentos chatarra. Existe asociación entre ansiedad en presencia de alimentos y nivel socioeconómico, y entre ansiedad en presencia de alimentos y estado nutricional (p = 0,01). En los escolares con sobrepeso y obesidad no se encontró asociación entre las variables del estudio. Existe ansiedad en presencia de alimentos en el 40 % por factores externos, en el 5 % por cansancio o aburrimiento y en el 11 % por sentimientos negativos. Conclusión: existe asociación entre ansiedad, nivel socioeconómico y estado nutricional. La ansiedad en presencia de alimentos se presentó en el 54,7 % de los casos.
