The (temporary) Covid-19 baby bust in Mexico.

In this paper, we investigate whether fertility and newborn health changed during the Covid-19 pandemic in Mexico. We use national administrative data and an event-study design to examine the impact of the Covid-19 pandemic on fertility and newborn health characteristics. Our findings suggest that Mexico's fertility declined temporarily as measured by conceptions that likely occurred during the stay-at-home order. Initially, the general fertility rate fell by 11-12 per cent but quickly rebounded and returned close to its original levels by the end of 2021. Newborn health also deteriorated during the pandemic. Instances of low birthweight and prematurity substantially increased, with both remaining elevated over the entire pandemic period.

Marriage and divorce during a pandemic: the impact of the COVID-19 pandemic on marital formation and dissolution in Mexico.

In this study, we consider the initial effects of the COVID-19 pandemic on family formation and dissolution. We use national microdata covering all marriages and divorces in Mexico, an event-study design and a difference-in-difference specification. Our findings indicate that over March through December of 2020, marriage rates declined by 54% and divorce rates by 43%. By the end of 2020, divorce rates recover back to baseline levels, but marriage rates remain 30% below the 2017-2019 baseline level. Overall, our findings suggest that marital dissolutions quickly recovered (6 months into the pandemic), but at the end of 2020, family formation remained at persistently lower levels.

Non-COVID-19 deaths in times of pandemic.

BACKGROUND AND OBJECTIVE: To investigate the effect of the COVID-19 pandemic on non-COVID-19 deaths in Mexico. METHODS: This study analyzes monthly administrative data on 15 different causes of death in Mexico from 2017 to 2020. The effects of the COVID-19 pandemic on non-COVID-19 deaths are conducted using a difference-in-differences methodology and an event study. RESULTS: The evidence shows mixed results. There is an increase in six causes of death: diabetes (36.8%), hypertension (25.8%), heart attacks (40.9%), bronchitis- asthma (24.2%), anemia (28.6%) and prostate cancer (21.4%). There is a decrease in two causes of death: traffic accidents (8.8%) and HIV (13.8%). There are null effects for seven causes of death: breast cancer, cerebrovascular disease, malnutrition, alcohol-related liver disease, renal insufficiency, homicides and suicides. CONCLUSIONS: The COVID-19 pandemic affected non-COVID-19 deaths caused by diseases that require intensive healthcare services. Conversely, this pandemic reduced social interactions, which contributed to a decrease on deaths such as traffic accidents.

The impact of the COVID-19 recession on Mexican households: evidence from employment and time use for men, women, and children.

This study examines changes in labor supply, income, and time allocation during the COVID-19 pandemic in Mexico. Using an event-study design, we show that the COVID-19 recession had severe negative consequences for Mexican households. In the first month of the pandemic, employment declined by 17 percentage points. Men recovered their employment faster than women, where men's employment approaches original levels by 2021Q2. Women, on the other hand, experienced persistent employment losses. Within-household, men also increased their time spent on household chores while neither gender (persistently) increased their time caring for others. Instead, children reduced their time spent on schoolwork by 25%.

The U-shaped crime recovery during COVID-19: evidence from national crime rates in Mexico.

The existing empirical evidence suggests a reduction in aggregate crime as a consequence of the COVID-19 lockdown. However, what happens when lockdown measures are relaxed? This paper considers how the COVID-19 pandemic affects crime rates throughout Mexico when the stay-at-home orders end. We use national crime data from Mexico's National Public Security System, which reports municipality-level rates on assault & battery, theft & property crime, fraud, drug crimes & extortion, and homicides. Our results show that the majority of crimes follow a U-shaped trend-when the lockdown ends-crimes rise back to pre-pandemic levels.

COVID-19 blues: Lockdowns and mental health-related google searches in Latin America.

RATIONALE: Stress process theory considers that actual and perceived isolation, caused by mobility restrictions from attempted containment of the COVID-19 pandemic, deteriorates mental health. OBJECTIVE: We examine the relationship between the COVID-19 lockdowns and mental health-related Google searches in 11 Latin American countries. We include the following countries: Argentina, Bolivia, Chile, Colombia, Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Uruguay. We also explore how changes in search patterns relate to income support policies and to COVID-19 death rates. METHOD: Using Google Trends data and an event-study design, as well as a difference-in-differences analysis, we investigate the association between country specific stay-at-home orders and internet searches including the following words: insomnia, stress, anxiety, sadness, depression, and suicide. RESULTS: We find three main patterns. First, searches for insomnia peak but then decline. Second, searches for stress, anxiety, and sadness increase and remain high throughout the lockdown. Third, there is no substantial change in depression-related or suicide-related searches after the lockdown. In terms of potential mechanisms, our results suggest that searches declined for suicide and insomnia following the passage of each country's income support, while in countries with higher COVID-19-related death rates, searches for insomnia, stress, and anxiety increased by more. CONCLUSIONS: Our results suggest that, in Latin America, Google searches for words associated with mild mental health disorders increased during the COVID-19 stay-at-home orders. Nonetheless, these conclusions should not be construed as a general population mental health deterioration, as we cannot verify that search indicators are accurately related to the users' current feelings and behaviors, and as internet users may not be representative of the population in this region.

COVID-19 and women's health: Examining changes in mental health and fertility.

Researchers have speculated that the economic and social consequences of COVID19 will harm women's health. This paper tests this claim in the immediate aftermath of Mexico City's COVID-19 stay-at-home order using call-center data. We use an event-study design to track calls for fertility decisions and mental health. Our findings indicate that mental health worsened during the pandemic. Anxiety calls increased substantially, with the effect being most pronounced for those over 45. Calls related to abortion fell in number, while pregnancy calls remained stable. The abortion effect is most pronounced for women between 15 and 30 and those with a high school degree.

The great crime recovery: Crimes against women during, and after, the COVID-19 lockdown in Mexico.

This paper considers whether the COVID-19 stay-at-home order affected crimes targeting women. To answer this question, we use national municipal-level crime data from Mexico's National Public Security System. The NPSS reports sexual crimes, lapses in alimony, domestic violence, and femicides. Using the NPSS, we track monthly changes in crimes targeting women using an event-study design. Our results show that lapses in alimony, sexual crimes, and domestic violence follow a U-shaped trend. Each crime declined during the stay-at-home order, and then rose back to pre-COVID levels by October. Then, we analyze potential mechanisms for the reduction in crimes against women. We find that infection risk, victim-criminal match, and banning the sale of alcohol are related to higher declines in crime.

Druglords don't stay at home: COVID-19 pandemic and crime patterns in Mexico City.

OBJECTIVE: To investigate the effect of the COVID-19 pandemic on conventional crime and organized crime in Mexico City, Mexico. METHODS: Mexico City's Attorney General's Office reported crime data, covering domestic violence, burglary, robbery, vehicle theft, assault-battery, homicides, kidnapping, and extortion. We use an event study for the intertemporal variation across the 16 districts (municipalities) in Mexico City for 2019 and 2020. RESULTS: We find a sharp decrease on crimes related to domestic violence, burglary, and vehicle theft; a decrease during some weeks on crimes related to assault-battery and extortion, and no effects on crimes related to robbery, kidnapping, and homicides. CONCLUSIONS: While our results show a decline in conventional crime during the COVID- 19 pandemic, organized crime remains steady. These findings have policy implications for catastrophic events around the world, as well as possible national security issues in Mexico.

Content and quality of 10,000 controlled trials in schizophrenia over 60 years.

OBJECTIVE: To carry out an up-to-date comprehensive survey of the content and quality of intervention trials relevant to the treatment of people with schizophrenia. DESIGN: Data were extracted and analyzed from 10,000 trials on the Cochrane Schizophrenia Group's Register. MAIN OUTCOME MEASURES: Source, type and date of publication, country of origin, language, size of trial, interventions, and outcome measures. RESULTS: In the last decade, there has been a great increase in the number of trials relevant to schizophrenia and an improvement in the accessibility to reports. The number of trials per year is rising (currently ∼600/year) with China now producing 25% of the annual total. The number of reports of trials is increasing at an even greater rate due to multiple publications. Drug trials still dominate (83%) although an increasing proportion of studies are now evaluating psychological therapies (21%). Trials remain small (median 60 people) and often employ new nonvalidated outcomes scales (2194 different scales were employed with every fifth trial introducing a new rating instrument). CONCLUSIONS: A more collaborative, pragmatic, and patient-centered approach is necessary to produce larger schizophrenia trials. Wider consultation and careful consideration of all relevant perspectives would result in trials with greater clinical utility and direct value to people with the illness and their families or carers.

Smoking behavior of Mexicans: patterns by birth-cohort, gender, and education.

OBJECTIVES: Little is known about historical smoking patterns in Mexico. Policy makers must rely on imprecise predictions of human or fiscal burdens from smoking-related diseases. In this paper we document intergenerational patterns of smoking, project them for future cohorts, and discuss those patterns in the context of Mexico's impressive economic growth. METHODS: We use retrospectively collected information to generate life-course smoking prevalence rates of five birth-cohorts, by gender and education. With dynamic panel data methods, we regress smoking rates on indicators of economic development. RESULTS: Smoking is most prevalent among men and the highly educated. Smoking rates peaked in the 1980s and have since decreased, slowly on average, and fastest among the highly educated. Development significantly contributed to this decline; a 1 % increase in development is associated with an average decline in smoking prevalence of 0.02 and 0.07 percentage points for women and men, respectively. CONCLUSION: Mexico's development may have triggered forces that decrease smoking, such as the spread of health information. Although smoking rates are falling, projections suggest that they will be persistently high for several future generations.
