Factors Associated with Early Sexual Activity in Adolescents Residing in an Urban Area of Northeastern Mexico Who Use WhatsApp or Facebook.

Early sexual activity has been associated with unplanned pregnancy and sexually transmitted infections. In recent decades, the prevalence of early sexual activity and social media use has increased. However, the relationship between these variables has been little studied. Consequently, we examined the relationships of some factors present in the family and personal environment with early sexual activity in adolescents who use and do not use the WhatsApp and Facebook platforms. Through a cross-sectional study, data from 1328 adolescents aged 13 to 19 years were analyzed. Data collection was carried out using a self-administered questionnaire. Of the total participants, 35.7% reported early sexual activity, and 37.7% reported using social networks such as WhatsApp and Facebook. The mean age of onset of sexual activity was 15.59 ± 1.56 years. Multivariate logistic regression analysis showed significant associations of not studying (adjusted OR 4.70; CI 95% 1.31-16.78), consuming alcohol (adjusted OR 3.71; CI 95% 2.44-5.65) and having parents who consumed alcoholic beverages in the home (adjusted OR 1.48; 95% CI 1.03-2.12) with ESA. In the family and personal environment, some factors favored early sexual activity in young people who used the WhatsApp and Facebook applications. This information should be used by authorities in the health and education sectors to strengthen preventive programs targeting health risk habits and behaviors in adolescents.

Asociación de la violencia obstétrica, control prenatal y embarazo no planeado con la prematurez / Association of obstetric violence, prenatal control, and unplanned pregnancy with prematurity

Resumen La prematurez (PM) neonatal es un problema mayor de salud pública en el mundo, debido a su frecuencia de presentación y los años de vida potencialmente perdidos; además, es la principal causa de muerte en menores de cinco años. Entre las consecuencias negativas de la PM están las discapacidades del aprendizaje, visual y auditiva. Múltiples son los factores asociados a la PM; algunos pueden ser detectados y modificados de forma oportuna en las consultas prenatales y también, en las preconcepcionales. Por otro lado, la PM no es solamente responsabilidad del prestador de los servicios de salud, sino también del sistema de salud, el cual, debe otorgar los recursos mínimos necesarios para monitorear y mantener a la embarazada en un estado óptimo de salud para evitarla, y en caso de presentarse, debe contar con la infraestructura hospitalaria básica que permita la viabilidad del producto y evitar su muerte. Aunado a lo anterior, se debe de considerar la responsabilidad de la paciente y su pareja, debido a que en ellos recae la obligación de llevar un estilo de vida saludable y acudir a las consultas preconcepcionales y control prenatal.

Abstract Neonatal prematurity (MP) is a major public health problem in the world, due to its presentation frequency and the years of life potentially lost; In addition, it is the main cause of death in children under five years of age. Among the negative consequences of MP are learning, visual and hearing disabilities. There are multiple factors associated with MP; some can be detected and modified in a timely manner in prenatal consultations and in preconception. On the other hand, MP is not only responsibility of the health service provider, but also of the health system, which must grant the minimum resources necessary to monitor and maintain the pregnant woman in an optimal state of health to avoid it, and if it occurs, the hospital must have the basic infrastructure that allows the viability of the product and prevents its death. In addition, the responsibility of the patient and her partner must be considered since they are obliged to lead a healthy lifestyle and attend preconception consultations and prenatal care.

Risk factors of non-adherence to guidelines for the prevention of COVID-19 among young adults with asthma in a region with a high risk of a COVID-19 outbreak.

OBJECTIVE: SARS-CoV-2 disease 2019 (COVID-19) is highly contagious and spreads rapidly. The application of preventive measures has proven to be the best strategy to minimize the number of patients and the dissemination of and deaths from COVID-19. The objective of this study was to determine the risk factors that limit the adherence of asthmatic patients to measures that prevent COVID-19 among residents of a region with a high risk of a COVID-19 outbreak. METHODS: Through a cross-sectional study, data from 2,372 participants aged 16-24 years were analyzed. To collect their information, a questionnaire was constructed using the Google Forms tool. Due to the prevention measures in place for COVID-19, the home quarantine of many people, and the lack of socialization, the questionnaire was distributed through email (Internet) and WhatsApp. A logistic regression analysis was performed to determine the relationship between the variables. RESULTS: The prevalence of asthma was 12.2%, and non-adherence to the guidelines for the prevention of COVID-19 was 53.1%. Approximately 30.8% of asthma patients did not comply with the basic prevention measures for COVID-19. The results of the logistic regression analysis showed that being male, active smoking, and believing that COVID-19 is not a more severe disease for people suffering from asthma than others were associated with non-adherence to the basic protection measures established in the guidelines for the prevention of COVID-19. CONCLUSIONS: It is important for health professionals to advise asthma patients to comply with the basic measures of protection against COVID-19 and timely use medications for asthma control.

Family, personal, and social factors associated with the non-use of contraceptive methods during the first sexual experience in adolescent women.

Unplanned pregnancy and sexually transmitted infections (STIs) in adolescents continue to be major health problems around the world. They are associated with sex that occurs without contraceptive protection. We determined the relationship of family, personal, and social factors with the non-use of any contraceptive method during the first sexual experience in 1409 adolescent women. The most significant risk factors were being less than 15 years of age and lacking knowledge and awareness about contraceptive methods. In the family environment, the risk factors were living in an incomplete family and the existence of a poor relationship among the father, the mother, and the adolescents. Socialization with friends who became sexually active at an early age was also associated with having sex for the first time without protection. This information should be used in sexual and reproductive education programmes to prevent unplanned pregnancy and STIs in adolescent women.

Unplanned pregnancy in adolescents: association with family structure, employed mother, and female friends with health-risk habits and behaviors.

Previous publications have suggested that living in a nonintact family household and socializing with girlfriends who smoke or who consume alcoholic beverages favor the development of health-risk habits and customs in adolescents. However, their relationship with unplanned pregnancy in adolescents has not been determined. We investigated the association between family structure, employed mother, and female friends with health-risk habits and behaviors with unplanned pregnancy in adolescents (n = 3,130). After adjusting for low maternal educational level and low family income, logistic regression analyses showed that having an employed mother and socializing with girlfriends who have health-risk habits or behaviors, rather than living in a nonintact family household, appear to be the most important health-risk factors for unplanned pregnancy in adolescents. It is important for health-care programs for adolescents to be revised and for their strategies be strengthened in order to reach the objectives for which they were created.

Association between family structure, maternal education level, and maternal employment with sedentary lifestyle in primary school-age children.

OBJECTIVE: To determine the association between family structure, maternal education level, and maternal employment with sedentary lifestyle in primary school-age children. METHOD: Data were obtained from 897 children aged 6 to 12 years. A questionnaire was used to collect information. Body mass index (BMI) was determined using the age- and gender-specific Centers for Disease Control and Prevention definition. Children were categorized as: normal weight (5(th) percentile≤BMI<85(th) percentile), at risk for overweight (85(th)≤BMI<95(th) percentile), overweight (≥ 95(th) percentile). For the analysis, overweight was defined as BMI at or above the 85(th) percentile for each gender. Adjusted odds ratios (adjusted ORs) for physical inactivity were determined using a logistic regression model. RESULTS: The prevalence of overweight was 40.7%, and of sedentary lifestyle, 57.2%. The percentage of non-intact families was 23.5%. Approximately 48.7% of the mothers had a non-acceptable educational level, and 38.8% of the mothers worked outside of the home. The logistic regression model showed that living in a non-intact family household (adjusted OR=1.67; 95% CI=1.04-2.66) is associated with sedentary lifestyle in overweight children. In the group of normal weight children, logistic regression analysis show that living in a non-intact family, having a mother with a non-acceptable education level, and having a mother who works outside of the home were not associated with sedentary lifestyle. CONCLUSION: Living in a non-intact family, more than low maternal educational level and having a working mother, appears to be associated with sedentary lifestyle in overweight primary school-age children.

Associação entre estrutura familiar, nível de escolaridade e emprego da mãe com estilo de vida sedentário em crianças em idade escolar primária / Association between family structure, maternal education level, and maternal employment with sedentary lifestyle in primary school-age children

OBJETIVO: Determinar a associação entre a estrutura familiar, o nível de escolaridade e emprego da mãe com o estilo de vida sedentário em crianças em idade escolar primária. MÉTODO: Foram obtidos os dados de 897 crianças com idade entre 6-12 anos. Foi utilizado um questionário para registrar as informações. O índice de massa corporal (IMC) foi determinado utilizando-se a definição específica para idade e sexo do Centro de Controle e Prevenção de Doenças. As crianças foram classificadas como: peso normal (5º-85º percentil), risco de sobrepeso (percentil > 85º e < 95º), sobrepeso (percentil > 95º). Para análise neste estudo, sobrepeso foi definido como IMC igual ou acima do 85º percentil para cada sexo. As razões de chance ajustadas (RCs ajustadas) foram determinadas para inatividade física utilizando o modelo de regressão logística. RESULTADOS: A prevalência de sobrepeso foi de 40,7%, e estilo de vida sedentário, 57,2%. O percentual de famílias de pais separados foi de 23,5%. Aproximadamente 48,7% das mães apresentaram um nível de escolaridade não aceitável, e 38,8% eram mães que trabalhavam fora de casa. Os resultados do modelo de regressão logística mostram que o fato de viver em um ambiente familiar com pais separados (RCs ajustadas = 1,67; IC 95% = 1,04-2,66) está associado ao estilo de vida sedentário em crianças com sobrepeso. No grupo de crianças com peso normal, a análise de regressão logística mostra que viver em uma família com pais separados, com a mãe apresentando nível de escolaridade não aceitável e/ou trabalhando fora de casa, não eram fatores associados a estilo de vida sedentário. CONCLUSÃO: Morar com uma família de pais separados, mais do que ter um baixo nível de escolaridade materno e uma mãe que trabalha fora, parece estar associado a um estilo de vida sedentário em crianças com sobrepeso em idade escolar primária.

[Association between unplanned pregnancy and adolescence onset asthma]. / Asociación entre embarazo no planeado y asma de inicio en la adolescencia.

BACKGROUND: The association between asthma and pregnancy has been documented previously. The relationship between unplanned pregnancy and onset asthma in adolescence has not been studied. OBJECTIVE: To determine the association between unplanned pregnancy and adolescence onset asthma. MATERIAL AND METHODS: A cross-sectional study was done gathering information about asthma, unplanned pregnancy, family atopy and active or passive smoking in 3,130 adolescents aged 13-19 years. Asthma diagnosis was established through a selfquestionnaire based on the International Study of Asthma and Allergy in Childhood. Odds ratios for asthma were determined using logistic regression model and chi-squared test. RESULTS: Mean age of the participants was 16.37 ± 1.93 years. The prevalence of active smoking was 16.1%, of passive smoking 40% and of family atopy 9.8%. From the pregnant adolescents (785), 59.5% reported had planned not to have a child before pregnancy. Prevalence of wheezing during the year prior to the study was 9.3% and of wheezing during the pregnancy 2%. The prevalence of adolescence onset asthma was 5.4%. The age of initiation of asthma in the adolescence was 14.75 ± 1.60 years. The analysis showed that unplanned pregnancy has a slight risk for the development of asthma during adolescence. (Crude OR=1.03; CI 95% 1.02-1.05; p=0.000). CONCLUSION: Unplanned pregnancy, family atopy, active smoking and smoking friends are associated with the onset-asthma in the adolescence.

ANTECEDENTES: la asociación entre embarazo y asma se ha documentado previamente. La relación entre embarazo no planeado y asma de inicio en la adolescencia no se ha estudiado. OBJETIVO: determinar la asociación entre embarazo no planeado y asma de inicio en la adolescencia. MATERIAL Y MÉTODOS: estudio transversal en el que se recogió información de asma, embarazo no planeado, atopia familiar y tabaquismo activo o pasivo en 3,130 adolescentes de 13-19 años de edad. El asma se diagnosticó mediante un cuestionario autoadministrado basado en el utilizado en el Estudio Internacional de Asma y Alergia en Niños (ISAAC por sus siglas en inglés). Se determinó la razón de momios para asma mediante regresión logística y chi cuadrada. RESULTADOS: la edad media de las participantes fue 16.37 ± 1.93 años. La prevalencia del tabaquismo activo fue 16.1%, del pasivo 40% y la atopia familiar 9.8%. De las adolescentes embarazadas (785), 59.5% anotó que no había planeado tener un hijo antes del embarazo. La prevalencia de sibilancias durante el último año fue 9.3% y de sibilancias durante el embarazo 2%. La prevalencia de asma de inicio en la adolescencia fue 5.4%. La edad de inicio de asma en la adolescencia fue 14.75 ± 1.60 años. El análisis muestra que el embarazo no planeado tiene un ligero riesgo de padecer asma de inicio en la adolescencia (RM cruda=1.03; IC 95% 1.02-1.05). CONCLUSIONES: el embarazo no planeado, la atopia familiar, el tabaquismo activo y el tabaquismo de las amigas se asocian con el asma de inicio en la adolescencia.

Smoking in non-student Mexican adolescents with asthma: relation with family structure, educational level, parental approval of smoking, parents who smoke, and smoking friends.

INTRODUCTION: The association between some factors of the familial and social environment with smoking in non-student adolescents with asthma has not been explored. The aim of the study was to determine the association between family structure, educational level, parental approval of smoking, parents who smoke, and smoking friends with smoking in non-student adolescents with asthma. SUBJECTS AND METHODS: In a cross-sectional study, data were obtained by means of a structured questionnaire applied to 4,778 non-student adolescents aged 13-18 years. Diagnosis of asthma was performed using a questionnaire based on the International Study of Asthma and Allergy in Childhood questionnaire. The smoking habit was determined by application of a self-administered questionnaire. Odds ratios (OR) were determined for smoking using logistic regression. RESULTS: From the total sample, asthma prevalence was 6.6% and of active smoking, 34.2%. Age at initiation of asthma symptoms was 5.15±3.52 years, and that of active smoking was 13.65±2.07 years. Percentage of non-intact family (40.1 vs. 32.7%) was greater in the group of adolescents with asthma. Logistic regression models show that parental approval of smoking (adjusted OR=5.57; 95% confidence interval=2.48-12.51) and smoking friends (adjusted OR=2.92; 95% confidence interval=1.04-8.19) are associated with smoking in non-student adolescents with asthma. CONCLUSION: In this study, parental approval of smoking and having friends who smoke appear to be associated with smoking among non-student adolescents with asthma.

Association between obesity and asthma in preschool Mexican children.

The elevated prevalence of obesity as well as of asthma in preschool children has prompted investigators to speculate that obesity in childhood might be a causal factor in the development of asthma. The results obtained to date are debatable. We investigated the association between obesity and asthma in 1,160 preschool Mexican children. Diagnosis of asthma was performed using the International Study of Asthma and Allergy in Childhood (ISAAC) questionnaire. The body mass index (BMI) in units of kg/m2 was determined, and children were categorized according to age- and gender-specific criteria, such as normal weight (5th-85th percentile), overweight (> or =85th and <95th percentile), and obesity (> or =95th percentile). Power test for logistic regression model was calculated. We found no association between overweight (adjusted OR = 1.02; 95% CI = 0.66-1.58), obesity (adjusted OR = 0.94; 95% CI = 0.68-1.30), and wheezing during the last year as determined by logistic regression model adjusted. We did not find an association between overweight, obesity, and asthma-associated hospitalizations. Further longitudinal studies are required to provide a better understanding of the relationship between obesity and asthma in preschool children.

[Association among familial atopy, smoking (passive and active), allergic rhinitis, labor environment and adult asthma]. / Asociación entre atopia familiar, tabaquismo (pasivo o activo), rinitis alérgica, ambiente laboral y asma del adulto.

BACKGROUND: Studies of association among parental atopy, tobacco exposure (passive or active) and adult asthma have provided conflicting results. OBJECTIVE: To determine the relationship among parental atopy, smoking, exposure to tobacco smoke, allergic rhinitis, work environment and asthma in adults. MATERIAL AND METHODS: In a population of 329,219 inhabitants of a geographically defined area in Northeastern of Mexico, we identified 791 cases of asthma. The patients were 20 to 54 years old, and were divided in three groups: with asthma in remission (263 patients), with symptoms since childhood (270 patients), and with asthma onset in adult age (258 patients). We included 793 randomly selected control subjects. Information on family atopy, passive and active smoking, allergic rhinitis and workplace conditions were collected by using a questionnaire. RESULTS: Parental atopy history, active smoking, allergic rhinitis and pollution in the workplace induce asthma symptoms. Exposure to smoking is a risk factor of persistence of asthma symptoms in adults (OR = 1.33; IC 95%, 1.07-1.66), but no of their development (OR = 1.10; IC 95%, 0.87-1.39). Working in a polluted environment had not significance in remission of asthma (OR =1.32; IC 95%, 0.95-1.85). CONCLUSIONS: Results support hypothesis that family atopy, active smoke, allergic rhinitis and pollution favor the persistence of asthma symptoms and increase the risk of asthma in adults.

Effect of allergic rhinitis, asthma and rhinobronchitis on dental malocclusion in adolescents.

OBJECTIVE: To determine the effect of allergic rhinitis (AR), asthma, rhinobronchitis (ARB) on dental malocclusion in adolescents. METHOD: This is a cross-sectional, observational, retrospective and sample descriptive study of 2556 adolescents aged 14-20 years. AR, asthma and ARB were defined by self-reported. Malocclusion was identified by direct physical examination. Data were analyzed by the SPSS 10.0 version statistical program, adjusted OR value (Odds Ratio) using a logistic regression model was determined, ji square was calculated, an 95% Confidence Intervals was used. Equal or smaller values of p < 0.05 were considered statistically significant. RESULTS: Percentage of male sex was 42.7% and female 57.3%. Prevalence of AR was 39.3%, asthma 6.9%, ARB 4.5%, and malocclusion, 37.2%. A higher percentage of malocclusion was found in adolescents with asthma (48.3% vs 36.3%). For the groups of asthma (adjusted OR = 1.78; p = 0.017) and RA (fit OR = 1.20, p = 0.032) were inferred that these pathologies to favor the malocclusion in adolescents, this did not happen with the group of RBA (OR fit = 0.81; p = 0.511). The prevalence of open bite was greater in adolescents with asthma (44.3% vs. 31.3%). For the asthma group (OR fit = 1.66; p = 0.037) we deduced that the development of anterior open bite is favored, this was not thus for the groups of RBA (OR fit = 1.01; p = 0.956) and RA (OR fit = 1.17; p = 0.071). Nor AR, asthma orARB have any effect on posterior open bite. CONCLUSIONS: Asthma is related to malocclusion in adolescents, particularly to anterior open bite. AR and ARB do not favor the development of malocclusion.
