• Study Type: observational
• Target: 1,038
• Locations: 1 country

Brief Summary

This is a longitudinal study of participants from two university communities in Chile. The primary objective is to examine the effect of a regional lockdown on alcohol and tobacco use, using a difference-in-difference analysis to obtain causal estimates of these COVID-19 policies.

Conditions

SARS-CoV-2 Infection; COVID-19

Keywords

Alcohol Drinking; Tobacco use; SARS-CoV-2; COVID-19; Epidemiology; Cohort Studies

Outcome Measures

Primary Outcomes (3)

• Weekly grams of alcohol use

  Consumption of alcohol during the past week measured in grams of pure alcohol

  Last week

• Frequency of heavy episodic drinking in the past month

  Frequency of consumption of five or more drinks on a single occasion during the past 30 days \[response range 0 to 10 and more times\]

  Last 30 days

• Quantity of cigarettes per day

  Average daily consumption of cigarettes during the last week

  Last week

Study Arms (2)

Students and academics Universidad La Frontera

The intervention consists of social distancing measures to curb the viral transmission of SARS-CoV-2. The Araucanía region was subject to lockdown in a different moment than the Coquimbo region, creating exogenous variation.

Behavioral: Lockdown and other social distancing measures

Students and academics Universidad Católica del Norte

The intervention consists of social distancing measures to curb the viral transmission of SARS-CoV-2. The Coquimbo region was subject to lockdown in a different moment than the Araucanía region, creating exogenous variation.

Behavioral: Lockdown and other social distancing measures

Interventions

Lockdown and other social distancing measures BEHAVIORAL

During the study period, the Chilean Ministry of Health established a five-step process for social distancing measures. These ranged from full lockdown (step 1) to almost no restrictions (step 5). Even under full lockdown, citizens were able to obtain permits for essential activities. Citizens had a maximum of two permits per week and were obtained in a virtual station of the Chilean Police Force (Carabineros de Chile).
