Haplin power analysis: a software module for power and sample size calculations in genetic association analyses of family triads and unrelated controls
Gjerdevik, Miriam; Jugessur, Astanand; Haaland, Øystein Ariansen; Romanowska, Julia; Lie, Rolv T.; Cordell, Heather J.; Gjessing, Håkon K. (Peer reviewed; Journal article, 2019-04-02)Background: Log-linear and multinomial modeling offer a flexible framework for genetic association analyses of offspring (child), parent-of-origin and maternal effects, based on genotype data from a variety of child-parent ... -
Health equity impact of community-initiated kangaroo mother care: a randomized controlled trial
Choudhary, Tarun Shankar; Mazumder, Sarmila; Haaland, Øystein Ariansen; Taneja, Sunita; Bahl, Rajiv; Martines, Jose Carlos; Bhan, Maharaj Kishan; Johansson, Kjell Arne; Sommerfelt, Halvor; Bhandari, Nita; Norheim, Ole Frithjof (Journal article; Peer reviewed, 2021)Background: Kangaroo mother care (KMC) can substantially enhance overall survival of low birthweight babies. In a large randomized controlled trial, we recently showed that supporting mothers to provide community initiated ... -
Isolated oral clefts and school grades: population-based cohort study from Norway
Gjerdevik, Miriam; Lie, Rolv T.; Haaland, Øystein Ariansen; Berg, Erik; Feragen, Kristin Billaud; Sivertsen, Åse (Journal article; Peer reviewed, 2021)Objective To compare school grades of adolescents in Norway born with isolated cleft with those of their unaffected peers. Design Population-based cohort study. Setting Norway. Patients A total of 347 419 individuals ... -
Life expectancy can increase by up to 10 years following sustained shifts towards healthier diets in the United Kingdom
Fadnes, Lars T.; Celis-Morales, Carlos; Økland, Jan-Magnus; Parra-Soto, Solange; Livingstone, Katherine M.; Ho, Frederick K.; Pell, Jill P.; Balakrishna, Rajiv; Javadi Arjmand, Elaheh; Johansson, Kjell Arne; Haaland, Øystein Ariansen; Mathers, John C. (Journal article; Peer reviewed, 2023)Adherence to healthy dietary patterns can prevent the development of non-communicable diseases and affect life expectancy. Here, using a prospective population-based cohort data from the UK Biobank, we show that sustained ... -
Maternal use of folic acid and multivitamin supplements and infant risk of birth defects in Norway, 1999–2013
Gildestad, Trude; Bjørge, Tone; Haaland, Øystein Ariansen; Klungsøyr, Kari; Vollset, Stein Emil; Øyen, Nina (Journal article; Peer reviewed, 2020)The association between folic acid supplementation and birth defects other than neural tube defects (NTD) remains unclear. We used a log-binomial regression model to investigate if periconceptional folic acid and/or ... -
A new approach to chromosome-wide analysis of X-linked markers identifies new associations in Asian and European case-parent triads of orofacial clefts
Skare, Øivind; Gjessing, Håkon K.; Gjerdevik, Miriam; Haaland, Øystein Ariansen; Romanowska, Julia; Lie, Rolv T.; Jugessur, Astanand (Peer reviewed; Journal article, 2017-09-06)Background: GWAS discoveries on the X-chromosome are underrepresented in the literature primarily because the analytical tools that have been applied were originally designed for autosomal markers. Our objective here is ... -
Parent-of-origin-environment interactions in case-parent triads with or without independent controls
Gjerdevik, Miriam; Haaland, Øystein Ariansen; Romanowska, Julia; Lie, Rolv T.; Jugessur, Astanand; Gjessing, Håkon K. (Peer reviewed; Journal article, 2018-03)With case–parent triad data, one can frequently deduce parent of origin of the child's alleles. This allows a parent‐of‐origin (PoO) effect to be estimated as the ratio of relative risks associated with the alleles inherited ... -
Protecting essential health services in low-income and middle-income countries and humanitarian settings while responding to the COVID-19 pandemic
Blanchet, Karl; Alwan, Ala; Antoine, Caroline; Cros, Marion Jane; Feroz, Ferozuddin; Amsalu Guracha, Tseguaneh; Haaland, Øystein Ariansen; Hailu, Alemayehu; Hangoma, Peter; Jamison, Dean T.; Memirie, Solomon Tessema; Miljeteig, Ingrid; Jan Naeem, Ahmad; Nam, Sara L.; Norheim, Ole Frithjof; Verguet, Stéphane; Watkins, David; Johansson, Kjell Arne (Journal article; Peer reviewed, 2020)In health outcomes terms, the poorest countries stand to lose the most from these disruptions. In this paper, we make the case for a rational approach to public sector health spending and decision making during and in the ... -
Socio-Economic Status and Reproduction among Adults Born with an Oral Cleft: A Population-Based Cohort Study in Norway
Berg, Erik; Sivertsen, Åse; Ariansen, Anja Maria Steinsland; Filip, Charles; Vindenes, Hallvard; Feragen, Kristin Judith Billaud; Moster, Dag; Lie, Rolv T.; Haaland, Øystein Ariansen (Peer reviewed; Journal article, 2016-09-15)Background: It has been reported that people born with orofacial clefts do worse in life than their peers regarding a range of social markers, such as academic achievement and reproduction. We have compared otherwise healthy ... -
Wavelet Screening identifies regions highly enriched for differentially methylated loci for orofacial clefts
Denault, William Robert Paul; Romanowska, Julia; Haaland, Øystein Ariansen; Lyle, Robert; Taylor, Jack A.; Xu, Zongli; Lie, Rolv T.; Gjessing, Håkon K.; Jugessur, Astanand (Journal article; Peer reviewed, 2021)DNA methylation is the most widely studied epigenetic mark in humans and plays an essential role in normal biological processes as well as in disease development. More focus has recently been placed on understanding ...
