Cohort profile: The Assessing Imperial Valley Respiratory Health and the Environment (AIRE) study.

BACKGROUND: The Children's Assessing Imperial Valley Respiratory Health and the Environment (AIRE) study is a prospective cohort study of environmental influences on respiratory health in a rural, southeastern region of California (CA), which aims to longitudinally examine the contribution of a drying saline lake to adverse health impacts in children. OBJECTIVES: This cohort was established through a community-academic partnership with the goal of assessing the health effects of childhood exposures to wind-blown particulate matter (PM) and inform public health action. We hypothesize that local PM sources are related to poorer children's respiratory health. POPULATION: Elementary school children in Imperial Valley, CA. DESIGN: Prospective cohort study. METHODS: Between 2017 and 2019, we collected baseline information on 731 children, then follow-up assessments yearly or twice-yearly since 2019. Data have been collected on children's respiratory health, demographics, household characteristics, physical activity and lifestyle, via questionnaires completed by parents or primary caregivers. In-person measurements, conducted since 2019, repeatedly assessed lung function, height, weight and blood pressure. Exposure to air pollutants has been assessed by multiple methods and individually assigned to participants using residential and school addresses. Health data will be linked to ambient and local sources of PM, during and preceding the study period to understand how spatiotemporal trends in these environmental exposures may relate to respiratory health. PRELIMINARY RESULTS: Analyses of respiratory symptoms indicate a high prevalence of allergies, bronchitic symptoms and wheezing. Asthma diagnosis was reported in 24% of children at enrolment, which exceeds both CA state and US national prevalence estimates for children. CONCLUSIONS: The Children's AIRE cohort, while focused on the health impacts of the drying Salton Sea and air quality in Imperial Valley, is poised to elucidate the growing threat of drying saline lakes and wind-blown dust sources to respiratory health worldwide, as sources of wind-blown dust emerge in our changing climate.

A rare etiology of frequent ventricular ectopy: Embolic complication of a venous iliac stent to the right ventricle.

Peripheral venous stent migration is an exceedingly rare complication of endovascular stenting. In this clinical vignette, we present a case of a 74-year-old male with a history of endo-venous laser ablation therapy of the right greater saphenous vein complicated with an occlusion requiring a left iliac vein stent. The patient presented to the clinic months after the procedure with complaints of palpitations. Multimodality imaging revealed a stent that had become dislodged and was now located in the right ventricle, trapped within the tricuspid valve apparatus.

Long-term suitability of an alternative host for rearing the sugarcane stalk borer parasitoid Tetrastichus howardi.

The continuous utilisation of an alternative host may influence parasitoid performance across successive generations due to conditioning in natal hosts. Tetrastichus howardi (Olliff) has successfully been reared using Tenebrio molitor L. pupae as a feasible alternative host. However, the extended rearing of T. howardi on this alternative host may impact the biological features of the parasitoids. Parasitoids were reared using T. molitor pupae for 30 consecutive generations. Quality criteria were assessed during the generations F5, F15, and F30, offering pupae of the target pest, Diatraea saccharalis (Fabr.), and compared with the F0 generation (parasitoids reared in D. saccharalis pupae). Criteria included assessments of parasitism performance, host selection, and wing form variation in the parasitoid wasps. Additionally, we examined the fecundity of T. howardi females that emerged from both hosts, considering their age, egg loading before and after one oviposition, as well as parasitism of sugarcane stalk borer pupae. Rearing T. howardi using pupae of T. molitor did not affect its biological traits or preference for the target pest for 30 generations. After parasitism, the parasitoid left the host pupa inside the stalk, and one oviposition was enough to kill D. saccharalis pupae and obtain viable parasitoid progeny. Female sexual maturation and egg loading occurred 72 and 96 h after parasitoid emergence. Egg-loading recovery after parasitism did not happen within 24 h. T. howardi can be reared for up to 30 generations using alternative hosts without compromising its parasitism performance or egg loading.

Patient Co-Creation Initiatives in the Ambulatory Care Setting during COVID-19: A Systematic Review.

Background and Objectives: The COVID-19 pandemic has led to significant changes in ambulatory care to meet new healthcare demands. Materials and Methods: A review of 21 articles focusing on patient co-creation initiatives during the pandemic shows that integrating patient feedback was crucial in transforming care delivery. Results: Joint efforts between healthcare professionals and patients led to new patient-focused telemedicine platforms, more efficient appointment systems, and improved safety measures. These adaptations overcame care barriers and maintained continuity of care. Key themes identified include monitoring community health standards, combining technology with patient-provider communication, and enhancing patient participation in health research. Conclusions: These co-creation efforts not only boosted patient satisfaction and outcomes but also demonstrated the potential for long-term healthcare innovations beyond the pandemic. The review further illuminates that co-creation in healthcare, particularly in tracking community health trends, is a practical strategy that involves diverse stakeholders in shaping healthcare delivery. The widespread adoption of co-creation in outpatient care during the pandemic highlights its role in driving patient-centered behavioral changes through innovative methods like crowdsourcing and dialogue conferencing. The review also recognizes that co-creation has been instrumental in responding to demographic changes, enhancing resources, creativity, and problem-solving in municipal-volunteer collaborations. Additionally, the evolution of technology in patient-provider communication, from initial resistance in the 1990s to its current critical role, particularly during the COVID-19 pandemic, underscores its importance in enhancing healthcare service delivery and patient data communication. The review also emphasizes the need for ethically and accessibly designed technology, especially for vulnerable groups, and highlights the significance of patient involvement in healthcare research, advocating for user-centered design and shared decision-making to create truly patient-centric interventions.

Large-scale and regional climatic influences on surface temperature and precipitation in the South Shetland Islands, northern Antarctic Peninsula.

Using data from SCAR observations, ERA5 reanalysis, and regional climate model simulations (RACMO), we examined the influence of large- and regional-scale climate forcing on temperature and precipitation variations in the South Shetland Islands (SSI). Specifically, we focused on understanding how regional climate indices influence the temporal variability of temperature and precipitation on the SSI. Our findings indicate that both large- and regional-scale climate indices significantly impact the interannual and seasonal temperature variability in the SSI. For instance, the Amundsen Sea Low, characterised by low-pressure systems over the Amundsen Sea, and sea ice extent in the northwestern part of the Weddell Sea, exert a strong influence on temperature variability (r from -0.64 to -0.87; p < 0.05). In contrast, precipitation variability in this region is primarily controlled by regional climatic indices. Particularly, anomalies in atmospheric and surface pressure over the Drake Passage region strongly regulate the interannual variability of precipitation in the SSI (r from -0.46 to -0.70; p < 0.05). Large-scale climatic indices demonstrate low but statistically significant correlations, including the Southern Annular Mode and deep convection in the central tropical Pacific. Given the importance of temperature and precipitation in the glacier changes, we recommend assessing the impact of the Drake region on SSI glaciers.

Autophagy as a Target for Non-Immune Intrinsic Functions of Programmed Cell Death-Ligand 1 in Cancer.

Autophagy is a catabolic process that is essential to the maintenance of homeostasis through the cellular recycling of damaged organelles or misfolded proteins, which sustains energy balance. Additionally, autophagy plays a dual role in modulating the development and progression of cancer and inducing a survival strategy in tumoral cells. Programmed cell death-ligand 1 (PD-L1) modulates the immune response and is responsible for maintaining self-tolerance. Because tumor cells exploit the PD-L1-PD-1 interaction to subvert the immune response, immunotherapy has been developed based on the use of PD-L1-blocking antibodies. Recent evidence has suggested a bidirectional regulation between autophagy and PD-L1 molecule expression in tumor cells. Moreover, the research into the intrinsic properties of PD-L1 has highlighted new functions that are advantageous to tumor cells. The relationship between autophagy and PD-L1 is complex and still not fully understood; its effects can be context-dependent and might differ between tumoral cells. This review refines our understanding of the non-immune intrinsic functions of PD-L1 and its potential influence on autophagy, how these could allow the survival of tumor cells, and what this means for the efficacy of anti-PD-L1 therapeutic strategies.

Dual Antiplatelet Therapy in Patients Aged 75 Years and Older with Coronary Artery Disease: A Meta-Analysis and Systematic Review.

Objectives: This systematic review and meta-analysis evaluates the safety and efficacy of dual antiplatelet therapy (DAPT) in elderly patients with acute coronary syndrome (ACS). Background: The safety and efficacy of DAPT in elderly patients with ACS is not well characterized. Methods: We performed a systematic literature review to identify clinical studies that reported safety and efficacy outcomes after DAPT for ACS in elderly patients. The primary outcomes of primary efficacy endpoint rates and bleeding event rates were reported as random effects risk ratio (RR) with 95% confidence interval. No prior ethical approval was required since all data are public. Results: Our search yielded 660 potential studies. We included 8 studies reporting on 29,217 patients. There was a higher risk of bleeding event rates in elderly patients treated with prasugrel or ticagrelor when compared to clopidogrel with a risk ratio of 1.17 (95% CI 1.08 to 1.27, p < 0.05). There was no difference in primary efficacy endpoint rates between elderly patients treated with prasugrel or ticagrelor when compared to clopidogrel with a risk ratio of 0.85 (95% CI 0.68 to 1.07, p=0.17). Conclusions: This systematic review and meta-analysis suggests that DAPT with prasugrel or ticagrelor compared to clopidogrel is associated with a higher risk of bleeding events in elderly patients with ACS. There was no difference in the primary efficacy endpoints between the two treatment groups.

Don't take the context out of the picture: Contextually shaped parents' and children's obesogenic behaviors in a marginalized area of Mexico City.

Santa Fe Gully zone is a marginalized area of Mexico City where nearly 39% of children live with either overweight or obesity. Despite the extensive research on obesogenic behaviors, studies frequently overlook the contexts where such behaviors occur. This qualitative study described individual and familial obesogenic behaviors among children with obesity from Santa Fe Gully, and explained how these behaviors might be contextually shaped. We used a grounded theory approach to investigate the process of development/maintenance of obesity in our sample. Fifteen participants (seven 10-year-olds with overweight or obesity and their parents) participated in nine art-based focus groups, and parents completed individual semi-structured interviews. Data were analyzed using a structured thematic content analysis. Results showed children's weight status was part of their identity, providing children with a familial 'fitting' sense while increasing psychosocial difficulties, leading to emotional overeating as a coping strategy. Parents' use of controlling and low-structured parenting practices reinforced children's emotional overeating and failed to regulate children's dietary and physical activity behaviors. Some low-structured parenting practices were guilt-motivated or fostered by socioeconomic and cultural factors (e.g., limited food access, unhealthy food exposure, community unsafety). Future interventions in Santa Fe Gully aimed at modifying obesogenic behaviors should incorporate systemic and ecological approaches to help participants navigate through contextual obstacles, as their behaviors should be analized considering the context where they occur.

Social capital in Mexico moderates the relationship of uncertainty and cooperation during the SARS-COV-2 pandemic.

This study proposes that, given the coronavirus disease 2019 pandemic, its sanitary restrictions, and the associated economic effects, citizens perceive higher uncertainty and tend to reduce their willingness to cooperate with others. Community social capital refers to a set of norms of reciprocity, trust, and civic engagement networks that promote trust, reciprocal help, and cooperation for mutual benefits. It is also suggested that it can help alleviate negative effects of the pandemic in communities, by reducing uncertainty and its harmful effects on cooperation. These hypotheses were tested in a sample of 565 inhabitants of Mexico, who answered an online survey with measurements of social capital, uncertainty, and willingness to cooperate in the face of the pandemic. The relationships between variables were analyzed in two structural equation models, which show adequate goodness of fit, where higher levels of uncertainty generated by the pandemic were associated with a greater disposition to noncooperation with others, while social capital moderated this relation decreasing negative effects of uncertainty on noncooperation. The value of social capital is discussed as a resource worth preserving and promoting in communities to strengthen them, so that they are better able to face health or economic contingencies.

Potential displacement of the native Tenuisvalvae notata by the invasive Cryptolaemus montrouzieri in South America suggested by differences in climate suitability.

Tenuisvalvae notata (Mulsant) (Coccinellidae) is a predatory ladybird beetle native to South America. It specializes in mealybugs prey (Pseudococcidae), but relatively little is known about its ecology. In contrast, the ladybird beetle Cryptolaemus montrouzieri Mulsant (Coccinellidae) is indigenous to Australia and has been introduced to many countries worldwide including Brazil for biological control of mealybugs. The potential impacts of these introductions to native coccinellids have rarely been considered. The software CLIMEX estimated the climate suitability for both species as reflected in the Ecoclimatic Index (EI). Much of South America, Africa, and Australia can be considered climatically suitable for both species, but in most cases, the climate is considerably more favorable for C. montrouzieri than T. notata, especially in South America. The CLIMEX model also suggests seasonal differences in growth conditions (e.g. rainfall and temperature) that could affect the phenology of both species. These models suggest that few locations in South America would be expected to provide T. notata climatic refugia from C. montrouzieri. Although other ecological factors will also be important, such as prey availability, this analysis suggests a strong potential for displacement of a native coccinellid throughout most of its range as a consequence of the invasion by an alien competitor.

Performance of a Low-Cost Sensor Community Air Monitoring Network in Imperial County, CA.

Air monitoring networks developed by communities have potential to reduce exposures and affect environmental health policy, yet there have been few performance evaluations of networks of these sensors in the field. We developed a network of over 40 air sensors in Imperial County, CA, which is delivering real-time data to local communities on levels of particulate matter. We report here on the performance of the Network to date by comparing the low-cost sensor readings to regulatory monitors for 4 years of operation (2015-2018) on a network-wide basis. Annual mean levels of PM10 did not differ statistically from regulatory annual means, but did for PM2.5 for two out of the 4 years. R2s from ordinary least square regression results ranged from 0.16 to 0.67 for PM10, and increased each year of operation. Sensor variability was higher among the Network monitors than the regulatory monitors. The Network identified a larger number of pollution episodes and identified under-reporting by the regulatory monitors. The participatory approach of the project resulted in increased engagement from local and state agencies and increased local knowledge about air quality, data interpretation, and health impacts. Community air monitoring networks have the potential to provide real-time reliable data to local populations.

Rate and impact of venous thromboembolism in patients with ST-segment elevation myocardial infarction: Analysis of the Nationwide Inpatient Sample database 2003-2013.

Venous thromboembolism (VTE) and coronary artery disease are major health issues that cause substantial morbidity and mortality. New data have emerged suggesting that these two conditions could have a close relationship. Thus, we sought to determine the trends in annual rate of VTE occurrence in patients with ST-segment elevation myocardial infarction (STEMI) and measure its impact on in-hospital mortality, bleeding complications, and cost and length of hospitalization. We queried the 2003-2013 Nationwide Inpatient Sample databases to identify adults with primary diagnosis of STEMI. VTE events were then allocated. Inpatient outcomes of patients with VTE were compared to those without VTE. Out of 2,495,757 hospitalizations for STEMI, VTE was diagnosed in 25,149 (1%) hospitalizations. Patients who experienced VTE were older (mean age: 67.5 vs 64.8, p < 0.01) and had a higher proportion of black patients (10.1% vs 7.7%, p < 0.001) and females (40.1% vs 35%, p < 0.001) compared to patients without VTE. There was an increasing trend in the rate of VTE during the study period (2003: 0.8% vs 2013: 1.0%, p < 0.001). Patients with VTE had a prolonged hospitalization (median: 9 vs 3 days, p < 0.001), increased cost, higher risk of gastrointestinal bleeding (OR: 2.13, p < 0.001), intracranial hemorrhage (OR: 2.14, p < 0.001), blood transfusions (OR: 1.94, p < 0.001), and mortality (OR: 1.39, p < 0.001). The rate of VTE occurrence in patients with STEMI in our study was 10 per 1000 admissions. VTE was associated with more bleeding complications, longer hospital stays, higher costs, and mortality. These findings suggest that a more aggressive approach for VTE prophylaxis may be warranted in this population.

Massive obliterative right heart thrombus presenting with near-syncope.

Intracardiac thrombi are commonly encountered as a complication of a recent myocardial infarction, heart failure, atrial fibrillation, or intracardiac devices. The prevalence of atrial thrombi in the absence of these risk factors is not well-described, but seems to be low. We present a case of a 51-year-old man with a massive mobile thrombus in the right heart extending through the tricuspid valve, diagnosed on echocardiography after presenting with a presyncopal episode.

Selective insecticides secure natural enemies action in cotton pest management.

Cotton hosts a variety of arthropod pests requiring intensive control mostly with insecticides, which in turn may impact beneficial insects and the environment. Therefore, insect control in cotton fields preconizes the use of selective insecticides that offer pest control but conserve natural enemies. In this work, we measured the impact of recommended insecticides on the abundance of predatory insects and predation upon sentinel preys in the field. Further, the survival of four key selected predatory insects of cotton ecosystem, representing chewing and sucking feeding habits and different pest species attacked [Chrysoperla externa Hagen, Eriopis connexa (Germar), Podisus nigrispinus (Dallas) and Orius insidiosus (Say)], were assessed when exposed to the dried residues of the tested insecticides. Mortality of sentinel prey caused by natural enemies was higher in areas treated with selective insecticides relative to the non-selective ones, and most of time similar to the untreated areas. Furthermore, areas treated with non-selective insecticides experienced prolonged impact between sprays depending on the insecticide applied. Seasonal abundance of predatory insects was 2× greater in fields under selective and untreated fields compared to those under non-selective recommendation. Survival of predators exposed to the dried residues of the selective insecticides pymetrozine, chlorantraniliprole, pyriproxyfen, and cyantraniliprole were greater than when exposed to the non-selective lambda-cyhalothrin, malathion, dimethoate, and thiamethoxam. Among the non-selective insecticides, malathion and dimethoate exhibited shorter residual time compared to the thiamethoxam and lambda-cyhalothrin + thiamethoxam. Therefore, the recommendation of selective insecticides provides benefits for cotton pest management by maintaining the action of the natural enemies present in the field.

Task difficulty modulates brain-behavior correlations in language production and cognitive control: Behavioral and fMRI evidence from a phonological go/no-go picture-naming paradigm.

Language production and cognitive control are complex processes that involve distinct yet interacting brain networks. However, the extent to which these processes interact and their neural bases have not been thoroughly examined. Here, we investigated the neural and behavioral bases of language production and cognitive control via a phonological go/no-go picture-naming task. Naming difficulty and cognitive control demands (i.e., conflict monitoring and response inhibition) were manipulated by varying the proportion of naming trials (go trials) and inhibition trials (no-go trials) across task runs. The results demonstrated that as task demands increased, participants' behavioral performance declined (i.e., longer reaction times on naming trials, more commission errors on inhibition trials) whereas brain activation generally increased. Increased activation was found not only within the language network but also in domain-general control regions. Additionally, right superior and inferior frontal and left supramarginal gyri were sensitive to increased task difficulty during both language production and response inhibition. We also found both positive and negative brain-behavior correlations. Most notably, increased activation in sensorimotor regions, such as precentral and postcentral gyri, was associated with better behavioral performance, in both successful picture naming and successful inhibition. Moreover, comparing the strength of correlations across conditions indicated that the brain-behavior correlations in sensorimotor regions that were associated with improved performance became stronger as task demands increased. Overall, our results suggest that cognitive control demands affect language production, and that successfully coping with increases in task difficulty relies on both language-specific and domain-general cognitive control regions.

Predation and behavioral changes in the neotropical lacewing Chrysoperla externa (Hagen) (Neuroptera: Chrysopidae) exposed to lambda-cyhalothrin.

Pyrethroid insecticides are widely recommended against various defoliating pest species, but usually lack efficacy against sucking pests such as aphids, which are preferred prey of lacewing larvae. Interaction of pyrethroids and lacewings are likely to occur in fields infested by both defoliating and sap-sucking pests and should provide a complementary control. Therefore, our study aimed to estimate dose-mortality curves and behavioral changes by Chrysoperla externa exposed to lambda-cyhalothrin. We tested the susceptibility of two populations from different locations and insecticide history exposure through topical application. Based on the LD50-calculated, the population exhibiting the greater LD50 was exposed to resistance enhancement (Sel) by treating larvae once for seven successive generations. The population with lower LD50 was kept without selection (Nsel). Subsequently, walking, predation and oviposition behavioral after exposure to dried insecticide residues were investigated. After seven generations with insecticide selection, the resistance rations between Sel and Nsel populations were 5.85- and 9.37-fold higher for larvae and 3.38- and 2.75-fold higher for adults, respectively. Selected females caged in partially treated arenas laid similar eggs number on both treated and untreated surfaces, while Nsel females laid fewer eggs on treated surfaces. Insecticide repellency was not observed in either population, although irritability was observed for Nsel larvae. Selected larvae confined on fully and partially treated surfaces walked further, for a longer time, and with greater speeds compared to Nsel larvae. Furthermore, Sel and Nsel larvae had reduced predation rates when confined on treated surfaces, and Nsel larvae consumed less prey than Sel larvae. Results indicate changes in susceptibility, behavior, and predation rate of C. externa following exposure to lambda-cyhalothrin.

Occult cancer in patients with deep-vein thrombosis in a general hospital at Mexico City: A pilot study.

BACKGROUND: We aimed to explore the frequency of occult cancer in patients with deep-vein thrombosis (DVT) at a general hospital in Mexico City. MATERIALS AND METHODS: From March 2012 to February 2015, all patients with primary DVT of lower extremities attended in the emergency department of our hospital were studied. Initially, all patients were evaluated with clinical history, physical examination, basic laboratories, abdominal ultrasound, chest X-ray, and duplex venous ultrasonography. In a case-by-case approach, if necessary, computed tomography, endoscopy, colonoscopy, and tumor markers were done. RESULTS: From 182 patients with primary DVT, 30 (16.5%) presented occult cancer: Thirteen males and 17 females, with an average age of 61 years. In males, prostate cancer prevailed (6/13, 46%); meanwhile, in females, pelvic gynecologic cancers predominated (7/17, 41%). CONCLUSION: Our results suggest that in Mexican patients with primary DVT, occult cancer is frequent.

Vertical heterostructures of layered metal chalcogenides by van der Waals epitaxy.

We report a facile chemical vapor deposition (CVD) growth of vertical heterostructures of layered metal dichalcogenides (MX2) enabled by van der Waals epitaxy. Few layers of MoS2, WS2, and WSe2 were grown uniformly onto microplates of SnS2 under mild CVD reaction conditions (<500 °C) and the heteroepitaxy between them was confirmed using cross-sectional transmission electron microscopy (TEM) and unequivocally characterized by resolving the large-area Moiré patterns that appeared on the basal planes of microplates in conventional TEM (nonsectioned). Additional photoluminescence peaks were observed in heterostructures of MoS2-SnS2, which can be understood with electronic structure calculations to likely result from electronic coupling and charge separation between MoS2 and SnS2 layers. This work opens up the exploration of large-area heterostructures of diverse MX2 nanomaterials as the material platform for electronic structure engineering of atomically thin two-dimensional (2D) semiconducting heterostructures and device applications.

Effects of a single course of prenatal betamethasone on dendritic development in dentate gyrus granular neurons and on spatial memory in rat offspring.

BACKGROUND: Preterm babies treated with synthetic glucocorticoids (sGC) in utero exhibit behavioral alterations and disturbances in brain maturation during infancy. However, the effects on dentate granule cell morphology and spatial memory in rats that were given clinically equivalent doses of antenatal betamethasone remain unclear. METHODS: Pregnant rats were randomly divided into the following two experimental groups: control (CON) and betamethasone-treated (BET) groups. At gestational day 20 (G20), BET dams were subcutaneously injected with a 0.17 mg/kg betamethasone solution, and CON animals received a similar volume of saline. At postnatal days 22 (P22) and P52, BET and CON offsprings were behaviorally evaluated in the Y-Maze test, and the dentate gyrus granular neurons were histologically analyzed. RESULTS: Animals prenatally treated with a single course of betamethasone exhibit a significant decrement in the dendritic outgrowth of dentate granule cells along with impaired spatial memory when evaluated at P52. Moreover, the body and brain weight of the BET group was significantly lower than the CON group at P0, P22, and P52. CONCLUSION: The current results indicate that a single course of betamethasone in pregnant rats produces significant neuronal and behavioral impairments of the offspring at adolescence along with a decrement in somatic and brain weights at each of the three ages evaluated.

Socio-economic indicators, dietary patterns, and physical activity as determinants of maternal obesity in middle-income countries: Evidences from a cohort study in Mexico.

Maternal obesity is one of the main public health problems at a world level. It is a multifactorial disease with multiple causes, and few studies exist on its dietary patterns, physical activity and social determinants. This work aims to identify determinants of maternal obesity in a middle income country. Research is based on a prospective cohort design. Data were collected using questionnaires applied to pregnant women. Three dietary patterns were identified, and only half of the women carry out physical activity. The regression analysis showed an association between overweight/obesity and the following variables: age 25 to 29 years old (3.8; CI 1.6-9.0), 30 to 34 years old (3.7; CI 1.2-11.6); health problems during pregnancy (2.1; CI 1.0-4.1); socio-economic income (1.73; CI 1.54-2.05); hypertension (2.7; CI 1.4-4.5); mild food insecurity (1.9; CI 1.0-3.8); moderate insecurity (3.7; CI 0.92-15.4); refined food dietary pattern (.76; CI.61-.95). The risk of increasing BMI during pregnancy mainly depends on socioeconomic and demographic variables such as age, educational level, income, food insecurity, and dietary pattern. This study's results could be used as evidences for the revision, planning, and adjustment of interventions for the prevention and management of maternal obesity, as a part of the national strategies against overweight and obesity.
