Breastfeeding duration is associated with higher adiposity at 6-8 months of age.

Breastfeeding (BF) has been identified as a protective factor against childhood obesity. However, evidence of the association between BF duration and adiposity remains inconclusive. Few studies have been conducted among Southeast Asian infants that have measured body composition during infancy using the gold standard stable isotope method.

Protein Quality Assessment of Follow-up Formula for Young Children and Ready-to-Use Therapeutic Foods: Recommendations by the FAO Expert Working Group in 2017.

The FAO of the UN convened an Expert Working Group meeting to provide recommendations related to protein quality evaluation of Follow-up Formula for Young Children (FUF-YC) and Ready-to-Use Therapeutic Foods (RUTFs). The protein and amino acid (AA) scoring patterns for the target age groups were defined and recommendations provided on the use of currently available protein and indispensable AA digestibility data. For FUF-YC, an age category of 1-2.

Objective: To carry out an inventory on the availability, challenges, and needs of dietary assessment (DA) methods in Africa as a pre-requisite to provide evidence, and set directions (strategies) for implementing common dietary methods and support web-research infrastructure across countries.

Methods: The inventory was performed within the framework of the "Africa's Study on Physical Activity and Dietary Assessment Methods" (AS-PADAM) project. It involves international institutional and African networks.

Risk factors of low vitamin D status in adolescent females in Kuwait: implications for high peak bone mass attainment.

Unlabelled: Risks of low vitamin D status in Kuwaiti adolescent girls are high parathyroid hormone (PTH), high waist/hip ratio, veiling and not having a private room. Low vitamin D status is likely to have a negative impact on their bone mass and accrual.

Introduction: Low serum 25-hydroxyvitamin D (25OHD) levels are repeatedly found in females in the Middle East, which is a cause for concern particularly for adolescent females.

An approach towards method development for untargeted urinary metabolite profiling in metabonomic research using UPLC/QToF MS.

The application of LC-MS for untargeted urinary metabolite profiling in metabonomic research has gained much interest in recent years. However, the effects of varying sample pre-treatments and LC conditions on generic metabolite profiling have not been studied. We aimed to evaluate the effects of varying experimental conditions on data acquisition in untargeted urinary metabolite profiling using UPLC/QToF MS.

The resurgence of the importance of vitamin D in bone health.

Dietary reference intakes (DRIs) for Vitamin D (VitD) have been traditionally established based on plasma 25-OHD concentration sufficient to prevent rickets and osteomalacia. While nutritional rickets is still prevalent in developing countries, hypovitaminosis D is becoming widespread around the world regardless the latitude. Emerging evidence has unravelled the physiological roles of VitD beyond calcium homeostasis.

Calcium requirements for Asian children and adolescents.

Calcium is important for bone health. Over the last 15 years, reference calcium intakes in Western countries have been revised upwards for maximizing bone mass at skeletal maturity and for prevention of osteoporotic fractures. Some of these reference figures have also been adopted for use in Asian countries.

Increased prevalence of constipation in pre-school children is attributable to under-consumption of plant foods: A community-based study.

Aim: To evaluate consumption of foods rich in dietary fibre and its relation to the prevalence of constipation in pre-school children.

Methods: In total, 368 children aged 3-5 years were randomly selected from kindergartens in Hong Kong. Constipation was confirmed by Rome-criteria.

Decision to breastfeed and early cessation of breastfeeding in infants below 6 months old--a population-based study of 3,204 infants in Hong Kong.

Breastfeeding rate has been low in Hong Kong over the last three decades. This has happened with concomitant rapid economic development and improved living standards. A population-based survey was conducted to evaluate factors influencing decision, duration and early cessation of breastfeeding in 3,204 full-term healthy infants under 6 months throughout Hong Kong in 1993.

A population-based survey on infant feeding practice (0-2 years) in Hong Kong: breastfeeding rate and patterns among 3,161 infants below 6 months old.

The prevalence of breastfeeding for the first 6 months in infants has been low in Hong Kong since the 1970s. In order to develop effective breastfeeding policies and promotion programs, an appraisal of feeding practices and factors related to initiation and early cessation of breastfeeding is necessary. A survey with a population-based representative sample was conducted to determine social-demographic, personal and cultural factors that influenced decision, duration and practice of infant feeding among infants 0-24 months old.

Generalized osteopenia in adolescent idiopathic scoliosis--association with abnormal pubertal growth, bone turnover, and calcium intake?

Study Design: A cross-sectional study in girls with adolescent idiopathic scoliosis (AIS) and healthy counterparts of similar age.

Objectives: To study the association of bone mass with anthropometric parameters, bone turnover, and calcium intake in 621 girls with AIS, aged 11-6-years, and compare the results with 300 healthy girls of similar age.

Summary Of Background Data: Generalized low bone mass has been documented in AIS, yet the cause of low bone mineral density in AIS is unknown.

Association of osteopenia with curve severity in adolescent idiopathic scoliosis: a study of 919 girls.

Generalized osteopenia and spinal deformity occur concomitantly in adolescent idiopathic scoliosis (AIS) during the peripubertal period. No large-scale study has been performed to reveal the link between scoliotic deformity and bone-mineral status in AIS. In a cross-sectional study, the extent of scoliotic-curve severity in relation to bone-mineral status was examined for 619 AIS girls and compared with those of 300 healthy non-AIS counterparts aged 11-16 years.

Improvement of feeding independence in end-stage cancer patients under palliative care--a prospective, uncontrolled study.

Purpose: Feeding independence is important to improve the quality of life (QOL) of patients receiving palliative care. Studies on feeding independence among cancer patients under palliative care are unavailable. This study aimed to evaluate the effectiveness of occupational therapy in promoting feeding independence in end-stage cancer patients in palliative care.

Generalized low bone mass of girls with adolescent idiopathic scoliosis is related to inadequate calcium intake and weight bearing physical activity in peripubertal period.

Generalized low bone mass has been well documented in patients with adolescent idiopathic scoliosis (AIS). However, studies linking calcium-intake (CA), weight-bearing physical-activity (PA) and bone mass of AIS are lacking. We aimed to study the relationship between CA, PA and bone mass in AIS girls and compared to those of healthy non-AIS controls during the peripubertal period.

Bone densitometry: which skeletal sites are best predicted by bone mass determinants?

Evaluation of bone mineral content/bone mass density (BMC/BMD) is important to determine bone mass development among adolescents in health and disease. It is uncertain at which skeletal site BMC/BMD is best predicted by bone mass determinants. On the other hand, intrapersonal BMC/BMD data can be clustered into a composite index score to facilitate correlation and outcome prediction analysis.

Calcium absorption measured by stable calcium isotopes ((42)Ca & (44)Ca) among Northern Chinese adolescents with low vitamin D status.

An adequate calcium intake and vitamin-D status is important for bone mineralization in adolescents. In Northern China, calcium intake and plasma vitamin-D level of adolescents is low due to low consumption of dairy foods and inadequate sunshine exposure. True fractional calcium absorption (TFCA) in Chinese adolescents has never been performed.

Use of stable calcium isotopes (42Ca & 44Ca) in evaluation of calcium absorption in Beijing adolescents with low vitamin D status.

Female adolescent populations with low calcium intakes and sub-optimal vitamin D status are found in northern China. Whether these individuals are able to adapt by enhancing calcium absorption and reducing calcium excretion for maximizing calcium retention is unknown. This study examined the association between true-fractional-calcium-absorption (TFCA), plasma 25-hydroxy-vitamin-D, and urinary calcium excretion among adolescents in Northern China.

Adjusting bone mass for differences in projected bone area and other confounding variables: an allometric perspective.

The traditional method of assessing bone mineral density (BMD; given by bone mineral content [BMC] divided by projected bone area [Ap], BMD = BMC/Ap) has come under strong criticism by various authors. Their criticism being that the projected bone "area" (Ap) will systematically underestimate the skeletal bone "volume" of taller subjects. To reduce the confounding effects of bone size, an alternative ratio has been proposed called bone mineral apparent density [BMAD = BMC/(Ap)3/2].
