OBJECTIVE: To assess whether exposure to standing, lifting, night work, or long work hours during 3 periods of pregnancy are associated with an increased risk of preterm or small-for-gestational-age birth. METHODS: The Pregnancy, Infection and Nutrition study is a prospective cohort with a nested case–control component that was conducted through clinic and hospital settings in Central North Carolina. A total of 1,908 women pregnant with a singleton gestation were recruited during prenatal… 

Occupational physical activities, working hours and outcome of pregnancy: findings from the Southampton Women’s Survey

There is a need for more research on trunk bending late in pregnancy, and on the relationship of work to reduced head circumference, as the findings on several other occupational exposures common among pregnant workers are reassuring.

Work activity in pregnancy, preventive measures, and the risk of preterm delivery.

Results showed association of PTD with demanding posture for at least 3 hours per day, whole-body vibrations, high job strain combined with low or moderate social support, and a cumulative index composed of nine occupational conditions.

Occupational lifting of heavy loads and preterm birth: a study within the Danish National Birth Cohort

In a society with social welfare and a highly regulated working environment, occupational lifting was associated with an increased risk of preterm birth.

The association of daily physical activity and birth outcome: a population-based cohort study

A sedentary lifestyle and paid work during the second trimester of pregnancy were found to be associated with a lower birth weight, while ‘bending and stooping’ and ‘working night shifts’ were associated withA higher birth weight.

Occupation and injuries: risk factors for preterm delivery

Data from the Iowa Health in Pregnancy Study was used to develop a method to correct for error in ultrasound measurement among suspected SGA infants, estimate the association of occupational stress on risk of PTD, and examine injury-related risk factors for PTD.

Preterm Delivery Risk in Relation to Maternal Occupational and Leisure Time Physical Activity Among Thai Women.

It is noted that heavy occupational physical exertion is associated with at least a doubling in PTD risk, which is less well delineated in this Thai population.

Physical Activity and Risk of Small-for-Gestational-Age Birth Among Predominantly Puerto Rican Women

Women with high total activity in mid-pregnancy had a decreased risk of SGA and high levels of sports/exercise were associated with an increased SGA risk without a significant dose–response association.

Exercise during pregnancy and the gestational age distribution: a cohort study.

Exercise performed during pregnancy shifted the GA distribution slightly upward resulting in reduced preterm births and slightly increased postterm births.



Maternal work during pregnancy and the risks of delivering a small-for-gestational-age or preterm infant.

The results indicate that prolonged standing and working late into pregnancy may increase the risk of delivering a small-for-gestational-age infant, whereas regular evening or night work may be a risk factor for preterm birth.

The effect of maternal work on fetal growth and duration of pregnancy: a prospective study

The data suggest that interventions to reduce physical exertion among pregnant women could improve birth outcome, as measured by an activity score.

Effect of maternal work activity on preterm birth and low birth weight.

A significant association between standing on the job and preterm birth was demonstrated when adjustment was made for the following variables in a logistic regression model: parity, smoking, education, caffeine use, marijuana use, race, gestational age at interview, and marital status.

Heavy lifting during pregnancy--a hazard to the fetus? A prospective study.

The preventive routines and regulations in Sweden may have helped to reduce possible risks from heavy lifting during pregnancy, although the risk estimates varied between different occupational categories.

The risk of prematurity and small-for-gestational-age birth in Mexico City: the effects of working conditions and antenatal leave.

OBJECTIVES This study examined the effect of working conditions, occupational stress, and antenatal leave on risk of small-for-gestational age and premature births in Mexico City. METHODS Over a

Is preterm delivery still related to physical working conditions in pregnancy?

The primary results showed that preterm birth did not vary significantly according to working conditions whereas it differed according to occupational group, discordant with other studies which underlined the excess of preterm births among women with strenuous working conditions.

Maternal Occupation and Pregnancy Outcome

The National Maternal and Infant Health Survey provided an opportunity to evaluate mothers' jobs in relation to preterm delivery, very low birthweight, moderately low birth Weight, small‐for‐gestational‐age (SGA) birth, stillbirth, and infant death.

Determinants of participation in an epidemiological study of preterm delivery.

Participation was affected only minimally by day or timing of recruitment, but inability to contact diminished substantially as the study continued, demonstrating that, overall, risk status was not lower among recruited women.
