description: The Minnesota Adolescent Community Cohort (MACC) Study is a population-based, longitudinal study that enrolled 3636 youth from Minnesota and 605 youth from comparison states age 12 to 16 years in 2000-2001. Participants were surveyed by telephone semi-annually about their tobacco-related attitudes and behaviors. The goals of the study were to evaluate the effects of the Minnesota Youth Tobacco Prevention Initiative and its shutdown on youth smoking patterns, and to better define the patterns of development of tobacco use in adolescents. A multilevel sample was constructed representing individuals, local jurisdictions and the entire state, and data were collected to characterize each of these levels. Major topics covered by the survey are cigarette use, nicotine dependence, alcohol use and dependence, cigarette access, quitting smoking, use of other tobacco products and marijuana, parent smoking habits, tobacco marketing, emotions and stress perceptions, and perceptions and opinions of smoke-free laws, tobacco companies, and tobacco age restrictions. Demographic information includes age, education, ethnicity, gender, marital status, and income level.
description: The primary aim of the MACC study was to evaluate local tobacco control programs in Minnesota, and the secondary aim was to better define the patterns of tobacco use in young adults and to evaluate the effects of tobacco control programs on these patterns.
description: The MACC Study employs a multilevel design, including a cohort sequential design of five ages at the individual level where individuals (adolescents) are surveyed every six months. These individuals are nested in GPUs (geo-political units) and there are longitudinal observations at the GPU level every six months as well. Finally, individuals and GPUs were randomly assigned a specific month within the six-month window for each observation; thus each month constitutes an observation in a time series design for the state of Minnesota.
description: The data are not weighted, and no weight variables are present in the data set.

description: A combination of probability and quota sampling methods (to assure equal age distribution) was used to establish the cohort. The goal was to recruit 3600 participants from Minnesota. These participants included 12 of each age from 12 to 16 years old from each of the 60 Minnesota GPUs. Recruitment was conducted by telephone by Clearwater Research, Inc., using modified random digit dial (MOD1) sampling to identify households with at least one teenager in the target age range within the target GPU. Within households, respondents were selected at random from among age quota cells that were still open for that GPU. Parent permission was obtained by telephone followed by permission from the chosen teenager before interviewing. In addition a comparison cohort (n=600) consisting of approximately 180 12-16 year olds from metropolitan Kansas City KS and MO, 240 from the rest of Kansas, 60 each from North and South Dakota and 60 from the upper peninsula of Michigan were recruited into the study. These states were chosen because as of 2000 they had devoted few resources from the Master Settlement Agreement to tobacco control and because they roughly corresponded to the demographics of Minnesota. Adolescents were interviewed by phone every six months, on the six-month anniversary of their previous interview.
