Adolescents´ lifestyle and bone health. The Tromsø Study, Fit Futures
(Doctoral thesis; Doktorgradsavhandling, 2015-12-16)Med data fra folkehelseundersøkelsen Fit Futures har vi sammenlignet norske ungdommers beintetthet med internasjonale referanseverdier og undersøkt sammenhengen mellom livsstilsfaktorer og beintetthet. Til tross for at Norges eldre er på verdenstoppen når det gjelder beinskjørhet (osteoporose) og beinbrudd, har dagens ungdommer like høy eller høyere beintetthet som jevngamle ungdommer i Europa ... -
The association between childhood fractures and adolescence bone outcomes: a population-based study, the Tromsø Study, Fit Futures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-16)<p><i>SUMMARY</i>: Childhood fracture may predict persistent skeletal fragility, but it may also reflect high physical activity which is beneficial to bone development. We observe a difference in the relationship between previous fracture and bone outcome across physical activity level and sex. Further elaboration on this variation is needed.</p> <p><i>PURPOSE</i>: Childhood fracture may be an ... -
Body weight and body mass index influence bone mineral density in late adolescence in a two-year follow-up study. The Tromsø Study: Fit Futures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-04)Determinants of bone acquisition in late adolescence and early adulthood are not well‐described. This 2‐year follow‐up study explored the associations of body weight (BW), body mass index (BMI), and changes in weight status with adolescent bone accretion in a sample of 651 adolescents (355 girls and 296 boys) between 15 and 19 years of age from The Tromsø Study: Fit Futures. This Norwegian ... -
Bone mineral density at the hip and its relation to fat mass and lean mass in adolescents: the Tromsø Study, Fit Futures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-19)<p><i>Background</i>: Positive association between body weight and bone mass is well established, and the concept of body mass index (BMI) is associated with higher areal bone mineral density (aBMD) and reduced fracture risk. BMI, that comprises both fat mass (FM) and lean mass (LM) may contribute to peak bone mass achievement in different ways. This study explored the influence of body composition ... -
Changes and tracking of bone mineral density in late adolescence: the Tromsø Study, Fit Futures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-08)<p><i>Summary</i>: Areal bone mineral density (aBMD) predicts future fracture risk. This study explores the development of aBMD and associated factors in Norwegian adolescents. Our results indicate a high degree of tracking of aBMD levels in adolescence. Anthropometric measures and lifestyle factors were associated with deviation from tracking.</p> <p><i>Purpose</i>: Norway has one of the highest ... -
Combined hormonal contraceptives and vitamin D metabolism in adolescent girls
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-31)Objective: Combined hormonal contraceptive (CHC) use has been associated with higher total 25-hydroxyvitamin D (25(OH)D) levels. Here, we investigate the relation between CHC use and vitamin D metabolism to elucidate its clinical interpretation. <p>Methods: The cross-sectional Fit Futures 1 included 1038 adolescents. Here, a subgroup of 182 girls with available 25(OH)D, 1,25-dihydroxyvitamin D ... -
Cross-sectional study of the differences between measured, perceived and desired body size and their relations with self-perceived health in young adults: The Tromsø Study - Fit Futures 2
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-09)Aims: The aim of this study was to explore the relationships between measured body size (body mass index (BMI)), perceived body size, weight change wishes and self-perceived health in young adults. Methods: The participants were recruited from a school-based population study in Norway, the Tromsø Study: Fit Futures 2, carried out in 2012–2013. A total of 629 young women and men (aged 18–23 years) ... -
Does the frequency and intensity of physical activity in adolescence have an impact on bone? The Tromsø Study, Fit Futures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-10)Background: Optimization of the genetic potential for bone accrual in early life may prevent future fractures. Possible modification factors include lifestyle factors such as nutrition and physical activity. Measured levels of bone mineral density (BMD) and bone mass content (BMC) are indicators of bone strength, and are correlated with fracture risk. This study explored the impact of self-reported ... -
Fett eller muskler - ett fett for beinmassen? : sammenhenger mellom fett- og muskelmasse og beintetthet (BMD), en tverrsnittsstudie basert på befolkningsundersøkelsen Tromsø V
(Master thesis; Mastergradsoppgave, 2009-06-15)Summary This thesis evaluates how fat body mass (FBM) and lean body mass (LBM) influence bone mineral density (BMD) in total body, weight bearing and non-weight bearing parts of the skeleton. It is a cross-sectional study based on absorptiometry data from a large population based study (Tromsø V). The project involved an initial quality control of the data, and includes data from 1354 men and women ... -
Fracture incidence rates in Norwegian children, The Tromsø Study, Fit Futures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-12-08)Summary: <br> This study describes childhood fracture rates in Norway, a country known for high fracture rates in the adult population. Fracture rates correspond with other reports from Scandinavia, although with a slightly higher proportion in girls. Indications of increased vulnerability during stages of puberty require further exploration. <p>Introduction: Fractures are common injuries during ... -
How Is Adolescent Bone Mass and Density Influenced by Early Life Body Size and Growth? The Tromsø Study: Fit Futures—A Longitudinal Cohort Study From Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-30)The effect of birth weight and childhood body mass index (BMI) on adolescents’ bone parameters is not established. The aim of this longitudinal, population‐based study was to investigate the association of birth weight, childhood BMI, and growth, with adolescent bone mass and bone density in a sample of 633 adolescents (48% girls) from The Tromsø Study: Fit Futures. This population‐based cohort study ... -
The influence of birth weight and length on bone mineral density and content in adolescence: The Tromsø Study, Fit Futures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-02)<p><i>Summary</i> The influence of birth weight and length on bone mineral parameters in adolescence is unclear. We found a positive association between birth size and bone mineral content, attenuated by lifestyle factors. This highlights the impact of environmental stimuli and lifestyle during growth.</p> <p><i>Purpose</i> The influence of birth weight and length on bone mineral density and ... -
The influence of snuff and smoking on bone accretion in late adolescence. The Tromsø study, Fit Futures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-27)Summary - Areal bone mineral density (aBMD) predicts future fracture risk. This study explores associations between use of tobacco and bone accretion in Norwegian adolescents. Our results indicate that use of snuff is negatively associated with accretion of aBMD in adolescence and may be a signal of increased future fracture risk.<p> <p>Purpose - Bone mineral accrual in childhood and adolescence ... -
