OBJECTIVES: Elevated Lipoprotein(a) (Lp[a]) is a well-known risk factor for cardiovascular disease. However, its roles in bone metabolism and fracture risk are unclear. We therefore investigated whether plasma Lp(a) levels were associated with bone mineral density (BMD) and incident hip fractures in a large cohort of postmenopausal women.

DESIGN: Post hoc analysis of data from the Women's Health Initiative (WHI), USA.

SETTING: 40 clinical centres in the USA.

PARTICIPANTS: The current analytical cohort consisted of 9698 white, postmenopausal women enrolled in the WHI, a national prospective study investigating determinants of chronic diseases including heart disease, breast and colorectal cancers and …

The Future Of Teratology Research Is In Vitro, Jarrod Bailey, Andrew Knight, Jonathan Balcombe

Jarrod Bailey, PhD

Birth defects induced by maternal exposure to exogenous agents during pregnancy are preventable, if the agents themselves can be identified and avoided. Billions of dollars and manhours have been dedicated to animal-based discovery and characterisation methods over decades. We show here, via a comprehensive systematic review and analysis of this data, that these methods constitute questionable science and pose a hazard to humans. Mean positive and negative predictivities barely exceed 50%; discordance among the species used is substantial; reliable extrapolation from animal data to humans is impossible, and virtually all known human teratogens have so far been identified in spite …

Gender Differences In Motivation To Resolve Eating And Body Image Concerns In College Students, Harold Merriman, C. Brahler, Laura Dinan, Lauren Finzer

C. Jayne Brahler

The objective of this study was to identify similarities and differences between college women and men with respect to their eating and body image concerns, weight fluctuation and level of motivation to resolve these concerns. 101 University of Dayton students participated in this study. Students completed an eating and body concern survey online.

Body image concerns were significantly greater for females compared to males (p=0.007) and significantly greater as motivation level to resolve the concerns increased (p=0.019). Eating concerns followed the same trends but did not reach statistical significance. Weight fluctuation in both genders increased significantly as motivation level increased …

The Mind-Body Connection: The Association Between Adolescent Locus Of Control And Indicators Of Physical Health, C. Brahler, James Cropper

C. Jayne Brahler

Locus of control (LOC) describes an individual’s generalized beliefs or expectancies that their reinforcements are under internal versus external control (1). An individual exhibits either an internal or external LOC. This study examines the link between LOC and selected health risk factors in adolescents. A convenience sample of 167 high school physical education students completed a 13-item LOC questionnaire based on Rotter’s 1966 instrument. Various anthropometric measurements, blood pressure, body mass index (BMI), and body fat were recorded on all subjects. A subsample of 61 female students received blood chemistry analysis that included a lipid profile, hemoglobin A1c (HbA1c), Apo …

Numerous Test Items In The Complete And Short Forms Of The Bot-2 Do Not Contribute Substantially To Motor Performance Assessments In Typically Developing Children Six To Ten Years Old, C. Brahler, Betsy Donahoe-Fillmore, Sara Mrowzinski, Susan Aebker, Megan Kreill

C. Jayne Brahler

The purposes of the current study were (1) to determine the magnitude of association between individual subtest items and the respective total subtest scores on the four subtests in the Bruininks-Oseretsky Test of Motor Proficiency, second edition (BOT-2) and (2) to review items on the BOT-2 Short Form. The correlation coefficients (r) between ranged from .865 to .071. Several items suffered from a ceiling effect, and four of the eight items on the Short Form for these four subtests had very low associations with their subtest total score. These results raise several issues with the BOT-2 that warrant further investigation.

Associations Of Adipose Tissue Architecture, Adipokines And Inflammatory Markers With Body Mass Index And Gestational Weight Gain In Non-Diabetic Pregnancies, Tiffany A. Moore Simas, Crina Boeras, Ningning Zhang, Olga Gaelikman, Katherine G. Leung, Nicole M. Wedick, Laura Robidoux, Jodi Adams Puleo, Mary M. Lee, Silvia Corvera, Milagros C. Rosal

Background: Some pregnancy weight gain is stored as adipose tissue (AT). Human AT depots vary in their capacity for expansion. Data suggests that subcutaneous (SQ) is adapted for healthy lipid storage. Conversely visceral (V) accumulation is associated with inflammation, obesity-related co-morbidities and Type 2 diabetes (T2DM) risk. We investigated SQ and VAT histologic architecture along with insulin, adipokines and inflammatory markers in relationship to prepregnancy BMI and gestational weight gain (GWG). Methods: Subset of non-diabetic singleton gravidas from the Pregnancy & Postpartum Observational Dietary Study (PPODS), undergoing Cesareans and consenting to SQ & VAT biopsies were included. Average adipocyte size …

Meaning Of The Family-Cap Policy For Poor Women: Contraceptive And Fertility Decision-Making, Diana Romero, Hannah Fortune-Greely, Jorge Verea, Debbie Salas-Lopez

Debbie Salas-Lopez MD, MPH

In 1996 the US Congress enacted welfare reform legislation. In addition to new lifetime time limits and work requirements for those receiving cash and other forms of social assistance, the states could impose policies pertaining to reproductive-related behaviors of poor women. One such policy is the so-called “family-cap,” which denies additional income support to poor women who have a baby while receiving cash assistance; 24 states have implemented such policies. The ostensible goal of the policy is to limit fertility among current cash assistance recipients. This pilot study sought to explore whether poor women in a family-cap state (NJ) base …
