Dietary Diversity in Cambodian Garment Workers: The Role of Free Lunch Provision
The objective of this paper is to compare food consumption by Cambodian garment workers with and without access to a free model lunch provision through a factory-based canteen. Data from an exploratory randomised controlled trial were analysed. In total, 223 female Cambodian garment workers were allocated to an intervention arm (six-month lunch provision) or a control arm. Dietary intake on workdays was assessed by qualitative 24-h recalls at baseline and twice at follow-ups during the period of lunch provision using the Food and Agricultural Organization (FAO) guideline on assessing womenÂŽs dietary diversity. In total, 158 participants provided complete data on the dietary intake over workdays at all interviews. Lunch provision resulted in a more frequent consumption of dark green leafy vegetables (DGLV), vitamin A-rich fruits, other fruits, and oils and fats during lunch breaks. In contrast, flesh meats, legumes, nuts and seeds, as well as sweets, were eaten at a lower frequency. Except for a higher consumption rate of vitamin A-rich fruits and a lower intake frequency of sweets, lunch provision had a less clear impact on total 24-h intake from different food groups and was not associated with a higher womenÂŽs dietary diversity score (WDDS). A more gap-oriented design of the lunch sets taking into account underutilised foods and the nutritional status of the workers is recommended
Exclusive breastfeeding and its effect on growth of Malawian infants: results from a cross-sectional study
Abstract
Background:
For the optimal nutrition of children under 2 years of age, it is considered important that they be exclusively breastfed for the first 6 months before being given complementary food.
Aims and Objectives:
A cross-sectional nutritional baseline survey was undertaken in 2011 in the Kasungu and Mzimba Districts of Malawi to assess the nutritional status of children under 2 years of age and its determinants in order to prepare a nutrition education intervention programme. The intention of this study was to assess the nutritional status of infants aged 0â<6 months with regard to food intake.
Methods:
Interviews were conducted on randomly selected families with children under 2 years; anthropometric measurements were obtained from mothers and their children. Only infants between 0 and <6 months were selected for analysis (n â=â 196). An ANCOVA test was performed on age of the infant with mothersâ height and weight as covariates.
Results:
Prevalence of stunting (infantsâ length-for-age Z-score (LAZ) <â2SD) was 39%, wasting (WLZ <â2SD) 2%, and underweight (WAZ <â2SD) 13%. Of the infants under 6 months, 43% were exclusively breastfed. Predominant breastfeeding and mixed breastfeeding were less common (21% and 36%, respectively). The ANCOVA confirmed the association between exclusive breastfeeding and LAZ and WAZ: exclusively breastfed infants had a higher mean (SE) LAZ (â1·13, 0·12) and WAZ (â0·41, 0·13) than infants not being exclusively breastfed (â1·59, 0·11, and â0·97, 0·11, respectively). There was no overall significant association between breastfeeding practice and WLZ.
Conclusion:
Exclusive breastfeeding of infants under 6 months is associated with higher mean LAZ and WAZ. Promotion of exclusive breastfeeding in low-income countries is important in preventing growth retardation

Methods: Interviews were conducted on randomly selected families with children under 2 years; anthropometric measurements were obtained from mothers and their children. Only infants between 0 and ,6 months were selected for analysis (n 5 196). An ANCOVA test was performed on age of the infant with mothers' height and weight as covariates. Results: Prevalence of stunting (infants' length-for-age Z-score (LAZ) ,22SD) was 39%, wasting (WLZ ,22SD) 2%, and underweight (WAZ ,22SD) 13%. Of the infants under 6 months, 43% were exclusively breastfed. Predominant breastfeeding and mixed breastfeeding were less common (21% and 36%, respectively). The ANCOVA confirmed the association between exclusive breastfeeding and LAZ and WAZ: exclusively breastfed infants had a higher mean (SE) LAZ (21.13, 0.12) and WAZ (20.41, 0.13) than infants not being exclusively breastfed (21.59, 0.11, and 20.97, 0.11, respectively).

Nuclear Reaction Network for Primordial Nucleosynthesis: a detailed analysis of rates, uncertainties and light nuclei yields
We analyze in details the standard Primordial Nucleosynthesis scenario. In
particular we discuss the key theoretical issues which are involved in a
detailed prediction of light nuclide abundances, as the weak reaction rates,
neutrino decoupling and nuclear rate modeling. We also perform a new analysis
of available data on the main nuclear processes entering the nucleosynthesis
reaction network, with particular stress on their uncertainties as well as on
their role in determining the corresponding uncertainties on light nuclide
theoretical estimates. The current status of theoretical versus experimental
results for 2H, 3He, 4He and 7Li is then discussed using the determination of
the baryon density as obtained from Cosmic Microwave Background anisotropies.Comment: LaTeX, 83 pages, 30 .pdf figures. Some typos in the units of

Tectono-stratigraphic response of the Sandino Forearc Basin (N-Costa Rica and W-Nicaragua) to episodes of rough crust and oblique subduction
The southern Central American active margin is a world-class site where past and
present subduction processes have been extensively studied. Tectonic erosion/accretion
and oblique/orthogonal subduction are thought to alternate in space and time
along the Middle American Trench. These processes may cause various responses
in the upper plate, such as uplift/subsidence, deformation, and volcanic arc migration/
shut-off. We present an updated stratigraphic framework of the Late Cretaceousâ
Cenozoic Sandino Forearc Basin (SFB) which provides evidence of
sedimentary response to tectonic events. Since its inception, the basin was predominantly
filled with deep-water volcaniclastic deposits. In contrast, shallow-water
deposits appeared episodically in the basin record and are considered as tectonic
event markers. The SFB stretches for about 300 km and varies in thickness from
5 km (southern part) to about 16 km (northern part). The drastic, along-basin, thickness
variation appears to be the result of (1) differential tectonic evolutions and (2)
differential rates of sediment supply. (1) The northern SFB did not experience major
tectonic events. In contrast, the reduced thickness of the southern SFB (5 km) is the
result of at least four uplift phases related to the collision/accretion of bathymetric
reliefs on the incoming plate: (i) the accretion of a buoyant oceanic plateau (Nicoya
Complex) during the middle Campanian; (ii) the collision of an oceanic plateau (?)
during the late DanianâSelandian; (iii) the collision/accretion of seamounts during
the late Eoceneâearly Oligocene; (iv) the collision of seamounts and ridges during
the PlioceneâHolocene. (2) The northwestward thickening of the SFB may have
been enhanced by high sediment supply in the Fonseca Gulf area which reflects
sourcing from wide, high relief drainage basins. In contrast, sedimentary input has
possibly been lower along the southern SFB, due to the proximity of the narrow,
lowland isthmus of southern Central America. Moreover, two phases of strongly
oblique subduction affected the margin, producing strike-slip faulting in the forearc
basin: (1) prior to the Farallon Plate breakup, an Oligocene transpressional phase
caused deformation and uplift of the basin depocenter, triggering shallowing-upward
of the Nicaraguan Isthmus in the central and northern SFB; (2) a PleistoceneâHolocene transtensional phase drives the NW-directed motion of a forearc sliver
and reactivation of the graben-bounding faults of the late Neogene Nicaraguan
Depression. We discuss arguments in favour of a Pliocene development of the
Nicaraguan Depression and propose that the Nicaraguan Isthmus, which is the
apparent rift shoulder of the depression, represents a structure inherited from the Oligocene
transpressional phase
German National Consensus Recommendations on Nutrition and Lifestyle in Pregnancy by the âHealthy Start - Young Family Networkâ
Diet and physical activity before and during pregnancy affect short- andlong-term health of mother and child. The energy needs at the end ofpregnancy increase only by about 10% compared to nonpregnant women. Anexcessive energy intake is undesirable since maternal overweight andexcessive weight gain can increase the risks for a high birth weight andlater child overweight and diabetes. Maternal weight at the beginning ofpregnancy is especially important for pregnancy outcome and childhealth. Women should strive to achieve normal weight already beforepregnancy. Regular physical activity can contribute to a healthy weightand to the health of pregnant women. The need for certain nutrientsincreases more than energy requirements. Before and during pregnancy,foods with a high content of essential nutrients should bepreferentially selected. Supplements should include folic acid andiodine, iron (in case of suboptimal iron stores), the omega-3 fatty aciddocosahexaenoic acid (in case of infrequent consumption of ocean fish)and vitamin D (in case of decreased sun exposure and decreasedendogenous vitamin D synthesis). Pregnant women should not smoke and notstay in rooms where others smoke or have smoked before (passivesmoking). Alcohol consumption should be avoided, since alcohol can harmunborn children
