Abstract Objectives We investigated the contributions of cigarette smoking to the age-related patterns of preterm (\37 weeks) birth (PTB) rates among African-American and White women within the context of lifelong neighborhood income. Methods Stratified and multilevel logistic regression analyses were performed on an Illinois transgenerational dataset of non-Hispanic White and African-American infants (1989–1991) and their mothers (1956–1976) with appended US census income information. Results: Among non-smoking African-American women (n = 20,107) with a lifelong residence in lower income neighborhoods, PTB rates decreased from 18.5 % for teens to 15.0 % for 30–35 year-olds, p \ 0.0001. The opposite pattern occurred among AfricanAmerican women smokers (n = 5936) with a lifelong residence in lower income neighborhoods, p \ 0.01. Among upwardly mobile African-American women smokers (n = 756), PTB rates increased from 11.1 % for teens to

24.9 % for 30–35 year-olds, p \ 0.05. Cigarette smoking was not associated with an age-related increase in PTB rates among African-American women with a lifelong residence in upper income neighborhoods. No subgroup of White women, even cigarette smokers with a lifelong residence in lower income neighborhoods, exhibited weathering with regard to PTB. Conclusions A weathering pattern of rising PTB rates with advancing age occurs only among African-American women cigarette smokers with an early-life or lifelong residence in lower income neighborhoods, underscoring the public health policy importance of targeted smoking cessation programs in eliminating the racial disparity in the age-related patterns of PTB rates.

Significance What is Already Known on the Subject? In contrast to \36 year-old White women, PTB rates remain elevated among \36 year-old African-American women. The limited available data suggests that cigarette smoking modifies the relationship between age and PTB rates among White and African-American women. What this Study Adds? A weathering pattern of rising PTB rates with advancing age occurs only among \36 year-old African-American women cigarette smokers with an early-life or l
