Tobacco consumption and nicotine dependence in Bengo Province, Angola: a community-based survey - dataset.

This dataset refers to the specific data on tobacco consumption, extracted from CardioBengo (DOI 10.1186/s12889-016-2759-9) community-based survey. For analysis, age was categorized into five 10-year age groups, 15 to 24; 25 to 34; 35 to 44; 45 to 54; and 55 to 64 years old. Education was categorized according to the number of completed schooling years as none; 1 to 4 years; 5 to 9 years; 10 years or more. Monthly family income in kwanzas was converted into USD, and categorized into groups of no income, under or equal to 150 USD, 151 to 299 USD and greater or equal to 300 USD. Participant’s consumption of alcoholic beverages during the last 12 months was recorded as none, daily, 5–6 days per week, 1–4 days a week, and 1–3 days per month. The area of residence (urban or rural) was classified as described for the area. Individuals were classified as current, ex-, and never users of tobacco. Current users were asked about the type of tobacco used: manufactured, hand-rolled, and smokeless tobacco. Smokers (manufactured and hand-rolled) were further grouped according to the frequency of consumption (≥1 and <6; ≥6 and <20; ≥20 cigarettes/day). Fagerström Test for Nicotine Dependence in Portuguese was used and categorized as 0 to 2 - very low; 3 to 4 - low; 5 - medium; 6 to 7 - high; 8 to 10 - very high.
