NCT03348566

Brief Summary

the investigators tested whether genetic variants near FADS cluster, which were recently identified to be signatures of adaptation to fish- and n-3 PUFAs-rich diet, interacted with these dietary factors on long-term change of body mass index (BMI).

Study Population

The Nurses' Health Study began in 1976, when 121,700 female registered nurses aged 30-55 y were recruited to complete a baseline questionnaire. the investigators included 11,323 women of European ancestry. Informed consent was obtained from all participants. The Health Professionals Follow-up Study The HPFS was initiated in 1986, and was composed of 51,529 male aged 40-75 y at baseline. This study included 6,833 men whose genotype data were available. Informed consent was obtained from all participants. The Women's Health Initiative (WHI) is a large, multiethnic, 40-center study that focuses on strategies for preventing heart disease, breast and colorectal cancer, and osteoporotic fractures in postmenopausal women. 6,254 Caucasians women with European ancestry were included. The design of Singapore Chinese Health Study (SCHS): Between 1993 and 1998, 63,257 Chinese between 45 and 74 in Singapore were enrolled. 5,264 subjects with genotyping data were included in this analysis.

You may qualify if:

  • ,323 women of European ancestry.
  • Informed consent was obtained from all participants. The DNA extraction methods, quality control measures,
  • SNPs genotyping and imputation data are available .
  • Both cases and controls with genotyping data are available based on GWASs

You may not qualify if:

  • participants without genetic data
