ABSTRACT

OBJECTIVES: To compare certain preconception health (PCH) behaviors and conditions among US-born (USB) and foreign-born (FB) mothers in Los Angeles County (LAC), regardless of race/ethnicity, and to determine if any identified differences vary among Asian/Pacific Islanders (API's) and Hispanics. METHODS: Data are from the 2012 Los Angeles Mommy and Baby study (n = 6252). PCH behaviors included tobacco use, multivitamin use, unintended pregnancy, and contraception use. PCH conditions comprised being overweight/obese, diabetes, asthma, hypertension, gum disease, and anemia. The relationship between nativity and each PCH behavior/condition was assessed using multivariable logistic regression models. RESULTS: USB women were more likely than FB women to smoke (AOR 2.12, 95 % CI 1.49-3.00), be overweight/obese (AOR 1.57, 95 % CI 1.30-1.90), and have asthma (AOR 2.04, 95 % CI 1.35-3.09) prior to pregnancy. They were less likely than FB women to use contraception before pregnancy (AOR 0.59, 95 % CI 0.49-0.72). USB Hispanics and API's were more likely than their FB counterparts to be overweight/obese (AOR 1.57, 95 % CI 1.23-2.01 and AOR 2.37, 95 % CI 1.58-3.56, respectively) and less likely to use contraception (AOR 0.58, 95 % CI 0.45-0.74 and AOR 0.46, 95 % CI 0.30-0.71, respectively). USB Hispanic mothers were more likely than their FB counterparts to smoke (AOR 2.47, 95 % CI 1.46-4.17), not take multivitamins (AOR 1.30, 95 % CI 1.02-1.66), and have asthma (AOR 2.35, 95 % CI 1.32-4.21) before pregnancy. CONCLUSIONS: US nativity is linked to negative PCH among LAC women, with many of these associations persisting among Hispanics and API's. As PCH profoundly impacts maternal and child health across the lifecourse, culturally-appropriate interventions that maintain positive behaviors among FB reproductive-aged women and encourage positive behaviors among USB women should be pursued.

ABSTRACT

Objectives. In order to comprehensively examine the risks and resources associated with racial-ethnic disparities in adverse obstetric outcomes, the Los Angeles County Department of Public Health and the University of California, Los Angeles, joined efforts to design and implement the 2007 Los Angeles Mommy and Baby (LAMB) study. This paper aims to present the conceptual frameworks underlying the study's development, highlight the successful collaboration between a research institution and local health department, describe the distinguishing characteristics of its methodology, and discuss the study's implications for research, programs, and policies. Methods. The LAMB study utilized a multilevel, multistage cluster design with a mixed-mode methodology for data collection. Two samples were ultimately produced: the multilevel sample (n = 4,518) and the augmented final sample (n = 6,264). Results. The LAMB study allowed us to collect multilevel data on the risks and resources associated with racial-ethnic disparities in adverse obstetric outcomes. Both samples were more likely to be Hispanic, aged 20-34 years, completed at least 12 years of schooling, and spoke English. Conclusions. The LAMB study represents the successful collaboration between an academic institution and local health department and is a theoretically based research database and surveillance system that informs effective programmatic and policy interventions to improve outcomes among LAC's varied demographic groups.

ABSTRACT

The field of corneal tissue engineering has made many strides in recent years. The challenges of engineering a biocompatible, mechanically stable, and optically transparent tissue are significant. To overcome these challenges, researchers have adopted two basic approaches: cell-based strategies for manipulating cells to create their own extracellular matrix, and scaffold-based strategies for providing strong and transparent matrices upon which to grow cells. Both strategies have met with some degree of success. In addition, recent advances have been made in innervating a tissue-engineered construct. Future work will need to focus on further improving mechanical stability of engineered constructs as well as improving the host response to implantation.
