Cholesterol at ages 6, 12 and 24 months: Tracking and associations with diet and maternal cholesterol in the Infant Cholesterol Study.

Background And Aims: There are indications for tracking of circulating total cholesterol concentration (TC) from childhood to later in life. An increased lifelong TC exposure increases the risk of developing atherosclerosis, however little is known about the determinants of TC early in life. We aimed to describe TC in Norwegian offspring aged 6, 12 and 24 months, and to explore if maternal TC, breastfeeding and offspring diet are associated with offspring TC.

Means of increasing response rates in a Norwegian dietary survey among infants - results from a pseudo-randomized pilot study.

Background: Postal surveys are widely used in scientific studies, including dietary surveys, but few studies about methods to increase participation in national dietary surveys are published. In the present study we compared response rates in a pilot study to a national dietary survey among infants using two different incentives (gift certificate or lottery), personalization in the form of handwritten name and address vs. a printed label and mode of sending out invitations (e-mail or postal invitation).

Validation of energy intake from a web-based food recall for children and adolescents.

The purpose of this study was to validate estimated energy intake from a web-based food recall, designed for children and adolescents. We directly compared energy intake to estimates of total energy expenditure, calculated from accelerometer outputs, combined with data on weight and sex or resting energy expenditure prediction equations. Children (8-9 years) and adolescents (12-14 years) were recruited through schools in Norway in 2013 (N = 253).

Evaluation of a Web-Based Food Record for Children Using Direct Unobtrusive Lunch Observations: A Validation Study.

Background: High-quality, Web-based dietary assessment tools for children are needed to reduce cost and improve user-friendliness when studying children's dietary practices.

Objective: To evaluate the first Web-based dietary assessment tool for children in Norway, the Web-based Food Record (WebFR), by comparing children's true school lunch intake with recordings in the WebFR, using direct unobtrusive observation as the reference method.

Methods: A total of 117 children, 8-9 years, from Bærum, Norway, were recruited from September to December 2013.
