Interindividual Variation in Chronic Inflammation in Northern Lao People's Democratic Republic
Livelihood and Dietary Transitions in Subsistence Populations of Northern Laos
Transition to a market economy and chronic psychosocial stress in northern Laos
OBJECTIVES: The indigenous population in northern Laos has experienced a transition from self-sufficiency to a market-oriented economy, which may have brought about unprecedented chronic psychosocial stress. This study examined the association between the transition to a market economy and urinary free cortisol (UFC) concentration as a stress biomarker among rural residents of three villages with different degrees of integration into the market e…
Impact of modernization on urinary concentrations of arsenic, cadmium, lead, and selenium in rural residents of Northern Laos
OBJECTIVES: The impacts of modernization on toxic heavy metal exposure and essential trace element intake in indigenous populations of subsistence societies are unknown. We assessed urinary trace element concentrations in rural residents of Northern Laos and examined associations with levels of modernization. METHODS: A cross-sectional study was conducted comprising 380 residents of three villages in Northern Laos with different levels of moderni…
Association between the dietary inflammatory index and disability in Japanese older people
Objectives: To examine the demographic and lifestyle characteristics related to the dietary inflammatory index (DIITM) score and to evaluate the association between DII score and disability among older people in Japan. Design: Cross-sectional design. The DII score was calculated from nutrient intake information obtained from a FFQ. Disability was assessed using the Tokyo Metropolitan Institute of Gerontology Index of Competence questionnaire. Ove…
Association study of CREBRF missense variant (rs373863828
The rs373863828-A allele may not directly affect the level of serum HDL-cholesterol independent of BMI. To confirm the present findings, association studies with large sample sizes and functional analyses are required
Reduced morning cortisol concentration in saliva was associated with obesity
OBJECTIVES: This study investigated morning salivary cortisol concentration in relation to total body fat composition among community-dwelling Papua New Guinean adults. METHODS: In addition to demographic and anthropometric measurements, saliva was collected in a single morning from 478 residents in Eastern Highlands Province and Madang Province. RESULTS: After adjusting for age, region, and occupation, the morning salivary cortisol concentration…
Association between sex inequality in animal protein intake and economic development in the P apua N ew G uinea highlands
OBJECTIVES: People in the Papua New Guinea Highlands consume sweet potatoes as their dietary staple; consumption of animal protein is limited. In such societies with marginal protein intake, the intra-household allocation of animal protein in terms of sex or age is of importance. The objective of this study was to investigate how the allocation pattern of protein-rich foods by sex and age is associated with economic development in the Papua New G…
Development, validation, and use of a semi‐quantitative food frequency questionnaire for assessing protein intake in Papua New Guinean Highlanders
OBJECTIVES: The aim of this article was to develop a semi-quantitative food frequency questionnaire (FFQ) and evaluate its validity to estimate habitual protein intake, and investigate current dietary protein intakes of Papua New Guinea (PNG) Highlanders. METHODS: A 32-item FFQ was developed and tested among 135 healthy male and female volunteers. The FFQ-estimated daily total and animal protein intakes were compared with biomarkers and 3-day Wei…
Association of protein intakes and variation of diet‐scalp hair nitrogen isotopic discrimination factor in P apua New G uinea highlanders
OBJECTIVES: We present new nitrogen isotopic discrimination factor between diets and scalp hairs (Δ(15) NHair-Diet : δ(15) NHair - δ(15) NDiet ) for indigenous residents in three communities in the Papua New Guinea Highlands who consumed various amounts and qualities of protein. The Δ(15) N is important for precise evaluation of the dietary habits of human populations; in both contemporary and traditional lifestyles. Several hypotheses have been …
DRD4 VNTR polymorphism in Oceanic populations
To study the origin of Polynesians and the gene flow from Polynesian ancestors to indigenous Melanesians, a 48-bp variable number of tandem repeats (VNTR) in exon 3 of the dopamine D4 receptor (DRD4) gene was investigated for six Austronesian (AN)-speaking populations—two in Tonga (Nuku’alofa and Ha’apai), three in Solomon Islands (Munda, Paradise, and Rawaki, of whom Rawaki was a Micronesian migrant group), and one in Papua New Guinea (Balopa), …
The serum leptin level and body mass index in Melanesian and Micronesian Solomon Islanders
Objectives: This study examined the association between the serum leptin level and body mass index (BMI) and the effects of urbanization and polymorphisms of leptin ( LEP ) or leptin receptor ( LEPR ) genes on the leptin level in three Solomon Islands populations. Methods: A Melanesian population living in a remote area (participants: 106 males and 106 females, ages: 18–74 years), a Melanesian population in an urban area (89 and 94, 18–79 years),…
Age and Gender Differences in the Physical Activity Patterns of Urban Schoolchildren in Korea and China
Physical activity in childhood is important as it may establish adult behavior. However, few studies on physical activity in children have been conducted, especially in Asian children. We performed anthropometric measurements of 159 school children in two grades (grade 5: 10-11 years old and grade 8: 13-14 years old) from urban areas of Korea (n=79) and China (n=80). The total daily energy expenditure (TEE) was estimated for 7 consecutive days us…
Overweight in Urban Schoolchildren Assessed by Body Mass Index and Body Fat Mass in Dalian, China
In order to assess overweight in urban schoolchildren (298 boys and 298 girls) aged 9-16 years in Dalian, China, their body height, weight, skinfolds at triceps, biceps, subscapular and suprailiac, and body circumferences of mid-upper arm, waist and hip were measured. The results showed that the prevalence of overweight, based on the United States Centers for Disease Control 2000 reference values using body mass index (BMI), was 22.9% in boys and…
No difference in serum leptin concentrations between urban-dwelling Austronesians and Non-Austronesians in Papua New Guinea
Pacific Islands populations can be broadly divided into Austronesians (AN) and Non-Austronesians (NAN); obesity and type 2 diabetes are prevalent in the former, although leptin levels in both groups have seldom been investigated. Thirty-seven (20 male and 17 female) adult pairs, matched by age and percent body fat, from AN-speaking Balopa and NAN-speaking Huli, all of whom migrated to settle in Port Moresby, the capital of Papua New Guinea, were …
Anthropometry of 5–19-year-old Tongan children with special interest in the high prevalence of obesity among adolescent girls
Among Tongan adolescents, obesity prevalence in girls was much higher than in boys, in association with fat accumulation in the former
Protein content and amino acid scores of sweet potatoes in Papua New Guinea Highlands
Protein content and amino acid scores of sweet potatoes were determined in Papua New Guinea Highlands where sweet potatoes contributed approximately 50% of the total protein intake. Major cultivars of sweet potatoes in the Tari basin and the Asaro valley, 15 in total, were sampled and their nitrogen and amino acid contents were analyzed. Sweet potatoes in the Tari basin and the Asaro valley contained, respectively, 1.4% and 0.8% of protein in fre…
Cardiovascular risk factors of migrants in Port Moresby from the highlands and island villages, Papua New Guinea
This study examined cardiovascular disease (CVD) risk factors, i.e., obesity, blood pressures, and serum lipoproteins and apoproteins, in relation to sociocultural characteristics in two rural-urban migrant populations (n = 173 adult males and females) in Port Moresby, the capital of Papua New Guinea. Tari migrants from the highlands and Balopa migrants from the islands differ genetically. More importantly, the lifestyle of the latter is more Wes…
