Quantile regression of tobacco tax pass-through in the UK 2017-2021: how have manufacturers passed through tax changes for different tobacco products in small retailers? Analysis at the national level and by neighbourhood of deprivation.

Background: The effectiveness of tax increases in reducing tobacco consumption relies on the tobacco retailers and producers passing on increases to consumers (tax pass-through). Previous UK research on supermarkets found heterogeneous levels of tax pass-through across the market segments and price distribution of tobacco products. This study uses data from small retailers across the UK to assess whether recent tax changes have been passed on to consumers and if this varies across the price distribution, between countries of the UK and by neighbourhood deprivation.

Geographical differences in the financial impacts of different forms of tobacco licence fees on small retailers in Scotland.

Objective: Retailer licencing fees are a promising avenue to regulate tobacco availability. However, they face strong opposition from retailers and the tobacco industry, who argue significant financial impacts. This study compares the impacts of different forms of tobacco licence schemes on retailers' profits in Scotland.

Maternal prenatal paracetamol ingestion and scholastic attainments of the offspring.

Fetal exposure to paracetamol (acetaminophen) has been shown to be associated with asthma and other atopic disorders, as well as behavioural problems including hyperactivity, in childhood. However, there is little information on scholastic abilities among children exposed to paracetamol in pregnancy. To determine whether there are any differences in scholastic abilities among the offspring of women who ingested paracetamol during pregnancy compared with non-exposed children.

A history of asthma may be associated with grandparents' exposures to stress and cigarette smoking.

Within human epidemiological studies, associations have been demonstrated between grandparental exposures during childhood and grandchildren's outcomes. A few studies have assessed whether asthma has ancestral associations with exposure to cigarette smoking, but results have been mixed so far. In this study we used four generations: (F0 great-grandparents, F1 grandparents, F2 parents, F3 study children) of the Avon Longitudinal Study of Parents and Children (ALSPAC) to determine whether there is evidence of associations between asthma in generations F2 or F3 and exposures to severe trauma in childhood and/or active cigarette smoking during the adolescence of grandmothers and grandfathers in generations F0 and F1 respectively, or of a history of a F0 or F1 grandmother smoking during pregnancy.

Is tobacco a driver of footfall among small retailers? A geographical analysis of tobacco purchasing using electronic point of sale data.

Objective: Opponents of policies designed to reduce tobacco retail availability argue that tobacco products are a vital driver of 'footfall' in small retailers. This study considers the changing contribution of tobacco to footfall and revenue among convenience stores across Britain, compares tobacco to other 'footfall driver' products and assesses whether tobacco's importance varies by neighbourhood deprivation and urban/rural status.

Methods: We conducted an analysis of electronic point of sale systems data from 1253 convenience stores in Britain in 4 weeks in 2016 and 2019.
