The revitalised Fonofale as a research paradigm: A perspective on Pacific sexuality and reproduction research

Research into Pacific peoples’ sexuality and reproduction is often complex and conflicts with social tapu. Historically, Pacific sexuality and reproduction research had been approached using a deficits-based lens with minimal congruence of Pacific cultural values. We offer a revitalised Fonofale model (Pulotu-Endemann, 1995) as a research paradigm that centres tapu in all considerations and decisions surrounding the research. This revitalised model offers a strengths-based approach that can promote valuable collection of, and meaningful engagement with data. We offer a case study which utilised this research paradigm as an overarching strategy. Te Tīpani Project was a mixed methods investigation into eighty-two Pacific tertiary students’ understandings of sexuality and reproduction. Pacific research methods and methodologies, including the Kakala model and Talanoa method supported the integration of the paradigm into components of the study. We encourage researchers to utilise this strategy to fulfil their research obligations, as facilitators and guardians (mana tiaki) of the research environment. Pacific research methods, methodologies and epistemologies hold an important place in the field of sensitive Pacific well-being research by enabling cultural consideration and responsiveness

A Polynesian-specific missense CETP variant alters the lipid profile

Summary: Identifying population-specific genetic variants associated with disease and disease-predisposing traits is important to provide insights into the genetic determinants of health and disease between populations, as well as furthering genomic justice. Various common pan-population polymorphisms at CETP associate with serum lipid profiles and cardiovascular disease. Here, sequencing of CETP identified a missense variant rs1597000001 (p.Pro177Leu) specific to Māori and Pacific people that associates with higher HDL-C and lower LDL-C levels. Each copy of the minor allele associated with higher HDL-C by 0.236 mmol/L and lower LDL-C by 0.133 mmol/L. The rs1597000001 effect on HDL-C is comparable with CETP Mendelian loss-of-function mutations that result in CETP deficiency, consistent with our data, which shows that rs1597000001 lowers CETP activity by 27.9%. This study highlights the potential of population-specific genetic analyses for improving equity in genomics and health outcomes for population groups underrepresented in genomic studies
