Note: Reference is “no” for all 4 types of stress. Modeling for breastfeeding cessation. OR score 1< indicates more likely to breastfeed; OR score 1> indicates less likely to breastfeed.
Variables Included in Model: age (continuous), race, language, education, inner-city residence, breastfeeding plan, parity and breastfeeding, depression, BMI, alcohol use, smoking.
Abbreviations: BF: Breastfeeding; NS: not significant.
aGlobal P-value.
bFinancial stress defined as answering yes to one of the following occurring during or in the month after pregnancy: big problems with money, moved to a new address.
cSelf-reported depression during or right after pregnancy.
dEmotional stress defined as answering yes to one of the following occurring during or in the month after pregnancy: family member had serious accident/illness, husband/partner had serious accident/illness, husband/partner died, friend/relative died.
eTraumatic stress defined as answering yes to one of the following occurring during or in the month after pregnancy: stayed in a shelter or needed emergency shelter, physical fights with partner/husband or someone else, husband/partner had legal trouble and/or went to jail, mother had legal trouble and/or went to jail, someone very close had a problem with drinking or drugs.
fPartner-Associated stress defined as answering yes to one of the following occurring during or in the month after pregnancy: separated from husband/partner, argued with husband/partner more often, husband/partner said he did not want pregnancy.

This calculated outcome was based on mothers self-report of length of breastfeeding (infant age when last received breastmilk) and age when the infant first received formula, other liquids cereal, or solid foods.
